I have a Solr index created with Nutch.
When trying to configure the elevator, I get a 404 error via the Solr Web Admin.
I added that to my solrconfig.xml:
<searchComponent name="elevator" class="solr.QueryElevationComponent" >
<!-- pick a fieldType to analyze queries -->
<str name="queryFieldType">string</str>
<str name="config-file">elevate.xml</str>
</searchComponent>
<requestHandler name="/elevate" class="solr.SearchHandler" startup="lazy">
<lst name="defaults">
<str name="echoParams">explicit</str>
</lst>
<arr name="last-components">
<str>elevator</str>
</arr>
</requestHandler>
{
"servlet":"default",
"message":"Not Found",
"url":"/solr/core01/elevate",
"status":"404"
}
Where can the error be?

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.
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>
<str name="exclusive">true</str>
<str name="editorialMarkerFieldName">test_elevated</str>
</searchComponent>
<requestHandler name="/elevate" class="solr.SearchHandler" startup="lazy">
<lst name="defaults">
<str name="echoParams">explicit</str>
<str name="defType">edismax</str>
<int name="rows">3</int>
<str name="fl">id,title,subtitle,course_code,cricos_code,course_introduction,outcome,page_url,[test_elevated],score</str>
<str name="q.alt">*:*</str>
</lst>
<arr name="last-components">
<str>elevator</str>
</arr>
</requestHandler>
Following is my configuration as per https://wiki.apache.org/solr/QueryElevationComponent
<searchComponent name="elevator" class="solr.QueryElevationComponent" startup="lazy">
<!-- pick a fieldType to analyze queries -->
<str name="queryFieldType">string</str>
<str name="config-file">elevate.xml</str>
</searchComponent>
<!-- A request handler for demonstrating the elevator component -->
<requestHandler name="/elevate" class="solr.SearchHandler">
<lst name="defaults">
<str name="echoParams">explicit</str>
</lst>
<arr name="last-components">
<str>elevator</str>
</arr>
</requestHandler>
The query to achieve the elevation was
$HOST/solr/collection/elevate?q=*:*&wt=json&elevatedIds=34464
But I don't see the document id of 34464 to be elevated.Can anyone please point out my mistake?
I am having an issue with by solr settings.
After a lot of investigation today, I found that its the spellcheck component which is causing the issue of Core Reload to hang.
If its turned off, all will run well and core can easily reload. However, when the spellcheck is on, the core wont reload instead hangs forever. Then the only way to get the project back alive is to stop solr, and delete the data folder then start solr again.
Here are the solr config settings for spell check:
<requestHandler name="/select" class="solr.SearchHandler">
<lst name="defaults">
<!-- Spell checking defaults -->
<str name="spellcheck.dictionary">default</str>
<str name="spellcheck">on</str>
<str name="spellcheck.count">5</str>
<str name="spellcheck.onlyMorePopular">false</str>
<str name="spellcheck.maxResultsForSuggest">5</str>
<str name="spellcheck.alternativeTermCount">2</str>
<str name="spellcheck.extendedResults">false</str>
<str name="spellcheck.collate">true</str>
<str name="spellcheck.maxCollations">3</str>
<str name="spellcheck.maxCollationTries">3</str>
<str name="spellcheck.collateExtendedResults">true</str>
</lst>
<arr name="last-components">
<str>spellcheck</str>
</arr>
</requestHandler>
<searchComponent name="spellcheck" class="solr.SpellCheckComponent">
<str name="queryAnalyzerFieldType">text_en_splitting</str>
<lst name="spellchecker">
<str name="name">default</str>
<str name="field">location_details</str>
<str name="classname">solr.DirectSolrSpellChecker</str>
<str name="buildOnCommit">true</str>
<float name="accuracy">0.5</float>
<float name="thresholdTokenFrequency">.01</float>
<int name="maxEdits">1</int>
<int name="minPrefix">3</int>
<int name="maxInspections">3</int>
<int name="minQueryLength">4</int>
<float name="maxQueryFrequency">0.001</float>
</lst>
</searchComponent>
.
Here is the field from schema:
<field name="location_details" type="text_en_splitting" indexed="true" stored="false" required="false" />
Basically, it is a bug in Solr. You need to just hide/comment/remove the following from your requestHandler:
<!--<str name="spellcheck.maxCollationTries">3</str> here is a bug, put this parameter in the actual query string instead -->
Furthermore, if you really need to use maxCollationTries, you can enter it as a Query parameter in your url instead.
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).
