Error creating a new SOLR Request Handler - solr

I am trying to make a query using SOLR Admin page:
I have defined a new SOLR Handler:
<requestHandler name="/globalmi-search-select" class="solr.SearchHandler">
<lst name="defaults">
<str name="echoParams">explicit</str>
<int name="rows">10</int>
<!-- ranking, boosting confiuration -->
<str name="defType">edismax</str>
<str name="qf">title^3.0 content^2.0 authors^1.0</str>
<str name="df">text</str>
<str name="fl">*,score</str>
<str name="mm">3<90% 6<75%</str>
</lst>
</requestHandler>
But when I try to hit a * query on this handler, I get the below response:
Please let me know if i am missing anything.

Solr Suggester taking too long to provide response

I am using Solr Suggester to provide suggestion in the search page of our application. But every suggestion request to Solr is taking too long to send response. I have tried with multiple lookup Impl such as AnalyzingLookupFactory, AnalyzingInfixLookupFactory, FuzzyLookupFactory etc.
Below is my configuration:
<searchComponent name="suggest" class="solr.SuggestComponent">
<lst name="suggester">
<str name="name">mySuggester</str>
<str name="lookupImpl">AnalyzingInfixLookupFactory</str>
<str name="dictionaryImpl">DocumentDictionaryFactory</str>
<str name="field">spell_suggest</str>
<str name="weightField">spell_suggest</str>
<str name="suggestAnalyzerFieldType">text_general</str>
<str name="buildOnStartup">false</str>
</lst>
<lst name="suggester">
<str name="name">altSuggester</str>
<str name="dictionaryImpl">DocumentDictionaryFactory</str>
<str name="lookupImpl">FuzzyLookupFactory</str>
<str name="field">spell_suggest</str>
<str name="weightField">spell_suggest</str>
<str name="suggestAnalyzerFieldType">text_general</str>
</lst>
</searchComponent>
<requestHandler name="/suggest" class="solr.SearchHandler" startup="lazy">
<lst name="defaults">
<!--<str name="suggest.dictionary">mySuggester</str> -->
<str name="suggest.dictionary">altSuggester</str>
<str name="suggest">true</str>
<str name="suggest.count">6</str>
<str name="spellcheck">true</str>
</lst>
<arr name="components">
<str>suggest</str>
</arr>
</requestHandler>
The response, with just 42000 indexed documents, is taking close to 5 to 7 seconds to provide response. This is impacting the functionality badly in the application
Following is my request: http://<myIP>:8983/solr/mycollection/suggest?df=spell_suggest&suggest=true&suggest.build=true&q=Vendor
Please suggest if I need to provide few more configurations or need to modify existing configurations to improve performance.
Thanks!
When you're issuing suggest.build each time, you're effectively asking for the suggestion index to be rebuilt from scratch each time you're querying the suggester.
It should only be rebuilt after changes if necessary (depending on which dictionaryImpl you're using).

Getting SolrException : Boosting query defined twice for query

I have created two query documents with names 'makeup', and 'make up' in elevate.xml.
When I execute the elevate solr query, I am getting exception "Boosting query defined twice for query".
whereas when I save two documents with names 'ChildCare', and 'Child Care', Solr is returning the results.
Below is my Solr query:
http://localhost:8983/solr/oneweb-collection/elevate?
q=*:*&defType=edismax&fl=id&fl=title&fl=subtitle&fl=course_code&
fl=cricos_code&fl=course_introduction&fl=outcome&fl=page_url&
fl=score&fl=%5Btafe_elevated%5D&rows=3&wt=json
When I save the document nodes, system internally replacing the spaces and storing the documents with same name.
What is the resolution for this issue?
Config for elevator:
<searchComponent name="elevator" class="solr.QueryElevationComponent" >
<str name="queryFieldType">text_general</str>
<str name="config-file">elevate.xml</str>
<str name="forceElevation">true</str>

How to design solr searchhandler in core mode and how to use it?

I'm using Solr 6.1.0 and not use cloud mode,
I has add searchhandler in solrconfig.xml and it's work, can see the search results
But when I use this searchhandler and add query in URL it'll error
Like this :
http://localhost:8983/solr/testcorea/contentsearch?indent=on&q=%22test%22&wt=json&shards=localhost:8983/solr/testcorea,localhost:8983/solr/testcoreb,localhost:8983/solr/testcorec,localhost:8983/solr/testcored
This is my searchhandler:
<requestHandler name="/contentsearch" class="solr.SearchHandler">
<lst name="defaults">
<str name="echoParams">explicit</str>
<str name="wt">json</str>
<str name="indent">true</str>
<str name="defType">edismax</str>
<str name="qf">
title^100.0 content^80.0 text^5.0
</str>
<str name="q">*:*</str>
<str name="indent">true</str>
<str name="rows">10</str>
<!-- Facet settings -->
<str name="facet">on</str>

<str name="facet.field">source_type</str>
<str name="hl">on</str>
<str name="hl.fl">title content</str>
<str name="hl.preserveMulti">true</str>
</lst>
<arr name="last-components">

</arr>
</requestHandler>

When I use solr default searchhandlr and query url it'll work
Like this :
http://localhost:8983/solr/testcorea/browse?indent=on&q=%22test%22&wt=json&shards=localhost:8983/solr/testcorea,localhost:8983/solr/testcoreb,localhost:8983/solr/testcorec,localhost:8983/solr/testcored
does anyone know what's different?
and why it does not work?
Thanks
Add highlighting parameters to URL.
Add hl=on and hl.fl=field_name to your url
ex:
hl.fl=title&hl=on&indent=on&q=test

solr - set fields as default search field - Using EdisMax

The following query works well for me
http://...:8983/solr/vault/select?q=White&defType=edismax&qf=VersionComments+VersionName
returns all the documents where version comments includes White
I try to omit the qf containing the fields names :
In solr config I write
<requestHandler name="/select" class="solr.SearchHandler">
<!-- default values for query parameters can be specified, these
will be overridden by parameters in the request
-->
<lst name="defaults">
<str name="echoParams">explicit</str>
<int name="rows">10</int>
<str name="df">PackageName</str>
<str name="df">Tag</str>
<str name="df">VersionComments</str>
<str name="df">VersionTag</str>
<str name="df">VersionName</str>
<str name="df">SKU</str>
<str name="df">SKUDesc</str>
</lst>
I restart the solr and create a full import.
Then I try using
http://...:8983/solr/vault/select?q=White&defType=edismax
But I dont get the document any as answer.
What am I doing wrong?
df is the default field and will only take effect if the qf is not defined and its a single definition field in the configuration.
You can check the below configuration with qt=edismax parameter :-
<requestHandler name="edismax" class="solr.SearchHandler" >
<lst name="defaults">
<str name="defType">edismax</str>
<str name="echoParams">explicit</str>
<str name="df">PackageName Tag VersionComments ....</str>
</lst>
</requestHandler>
You can use qf (query field) with weight indication.
<requestHandler name="/select" class="solr.SearchHandler">
<!-- default values for query parameters can be specified, these
will be overridden by parameters in the request
-->
<lst name="defaults">
<str name="echoParams">explicit</str>
<int name="rows">10</int>
<!--
[....]
-->
<str name="qf">PackageName^40.0 Tag^10.0 VersionComments^5.0 VersionTag^4.0</str>
<!--
[....]
-->
</lst>
</requestHandler>
Solr 4.8.1 We can make default as follows. by editing solrconfig.xml
<requestHandler name="/clustering" startup="lazy" enable="${solr.clustering.enabled:false}" class="solr.SearchHandler">
<lst name="defaults">
<!-- Configure the remaining request handler parameters. -->
<str name="defType">edismax</str>
<str name="qf">
text^0.5 features^1.0 name^1.2 sku^1.5 id^10.0 manu^1.1 cat^1.4
</str>
<str name="q.alt">*:*</str>
<str name="rows">10</str>
<str name="fl">*,score</str>
</lst>
<arr name="last-components">
<str>clustering</str>
</arr>
</requestHandler>

Request handle solrconfig.xml Spellchecker

I am trying to set up spellchecker, according to solr documentation. But when I am testing, I don't have any suggestion. My piece of code follows:
<searchComponent name="spellcheck" class="solr.SpellCheckComponent">
<str name="queryAnalyzerFieldType">textSpell</str>
<lst name="spellchecker">
<str name="classname">solr.IndexBasedSpellChecker</str>
<str name="name">default</str>
<str name="field">name</str>
<str name="spellcheckIndexDir">./spellchecker</str>
</lst>
<str name="queryAnalyzerFieldType">textSpell</str>
</searchComponent>
<requestHandler name="/spellcheck" class="solr.SearchHandler">
<lst name="defaults">
<str name="echoParams">explicit</str>
<!-- Optional, must match spell checker's name as defined above, defaults to "default" -->
<str name="spellcheck.dictionary">default</str>
<!-- omp = Only More Popular -->
<str name="spellcheck.onlyMorePopular">false</str>
<!-- exr = Extended Results -->
<str name="spellcheck.extendedResults">false</str>
<!-- The number of suggestions to return -->
<str name="spellcheck.count">1</str>
</lst>
<arr name="last-components">
<str>spellcheck</str>
</arr>
</requestHandler>
The query I send to Solr:
q=%2B%28text%3A%28gasal%29%29&suggestField=contentOriginal&ontologySeed=gasal&spellcheck.build=true&spellcheck.q=gasal&spellcheck=true&spellcheck.collate=true&hl=true&hl.snippets=5&hl.fl=text&hl.fl=text&rows=12&start=0&qt=%2Fsuggestprobabilistic
Does anybody know why?? Thanks in advance
First, don't repeat queryAnalyzerFieldType twice in the component configuration.
It is recommended not to use a /spellcheck handler but instead to bind the spellcheck component to the standard query handler (or dismax if it is what you use) like this:
<requestHandler name="standard" class="solr.SearchHandler" default="true">
<lst name="defaults">
...
</lst>
<arr name="last-components">
<str>spellcheck</str>
...
</arr>
</requestHandler>
You can then call it like this:
http://localhost:8983/solr/select?q=komputer&spellcheck=true
Also don't forget to build the spellcheck dictionary before you use it:
http://localhost:8983/solr/select/?q=*:*&spellcheck=true&spellcheck.build=true
You can force the dictionary to build at each commit by configuring it in the component:
<searchComponent name="spellcheck" class="solr.SpellCheckComponent">
<str name="queryAnalyzerFieldType">textSpell</str>
<lst name="spellchecker">
<str name="classname">solr.IndexBasedSpellChecker</str>
<str name="name">default</str>
<str name="field">name</str>
<str name="spellcheckIndexDir">./spellchecker1</str>
<str name="buildOnCommit">true</str>
</lst>
</searchComponent>
Finally, make sure that your name field is really an indexed field of type textSpell and that it contains enough content to build a good dictionary. In my case, I have a field named spellchecker that is populated from a couple of fields of my index (using copyField instructions in the schema).
