I am trying to insert data to SOLR using HardCommit. By default value of openSearcher=false in solrConfig.xml. I want to change openSearcher=true through JAVA code. Donot want to make change to SOLR.config.xml. Is there any way to do that??
Thanks
You should be able to do that with Config API. You could check current configuration by firing GET request at /config endpoint. E.g
http://localhost:8983/solr/collection-name/config
and set some property with command like this:
curl http://localhost:8983/solr/collection-name/config
-H 'Content-type:application/json' -d
'{
"set-property": {
"updateHandler.autoCommit.openSearcher": true
}
}'
This could be of course done in Java code, by using some popular HTTP client or by firing your implementation of abstract SolrRequest in SolrJ

I'm setting up my first Solr server via docker using solr:8.11.1-slim. I am gonna use the schema API to set up the schema for my core whose name is 'products'.
While reading the docs there seems to be false info on the docs for field types:
https://solr.apache.org/guide/8_11/field-types-included-with-solr.html
vs.
https://solr.apache.org/guide/8_11/schema-api.html
I followed the first guide to get info on what field types I can specify and am trying to send requests based on the second doc such as this:
{ 'add-field': { "name":"latlong", "type":"LatLongPointSpatialField", "multiValued":False, "stored":True, 'indexed': True } },
but Solr gives me back errors such as:
org.apache.solr.api.ApiBag$ExceptionWithErrObject: error processing commands, errors: [{add-field={name=latlong, type=LatLongPointSpatialField, multiValued=false, stored=true, indexed=true}, errorMessages=[Field 'latlong': Field type 'LatLongPointSpatialField' not found
So what gives? Am I misreading the docs or are they wrong or is something wrong with the solr 8.11.1 image in docker? Why does it not accept the field types I'm providing?
Thanks for your help ahead of time.
I have been trying to leverage the PrettyPrint feature to display the result of my API that is using Apache Camel. Here is the context. I have this route in my code
// Route Definition for processing Health check request
from("direct:processHealthCheckRequest")
.routeId("health")
.setHeader(Exchange.HTTP_RESPONSE_CODE, constant(200))
.setBody(constant(healthCheckResponse));
When I'm using Postman to test my API, the display is in pretty mode even though it is not set to true, like so
{
"status": "UP"
}
Now when I'm using the following code to set the PrettyPrint to false, I'm still getting the same result. It looks like the PrettyPrint feature is not working as it is supposed to
// Route Definition for processing Health check request
from("direct:processHealthCheckRequest")
.routeId("health")
.setHeader(Exchange.HTTP_RESPONSE_CODE, constant(200))
.setBody(constant(healthCheckResponse))
.unmarshal()
.json(JsonLibrary.Jackson, HealthCheckResponse.class, false);
I'm expecting the result to be displayed on one line like here without changing the type from JSON to string.
{"status": "UP"}
Could someone please advice on this?
I've bumped into the same issue always when manually setting the HTTP_RESPONSE_CODE header. I don't know why it technically happens - without it the HTTP response always returns proper JSON for me.
Setting CONTENT_TYPE header to application/json has solved it:
.setHeader(Exchange.CONTENT_TYPE, constant("application/json"))
The solution that finally worked was to set the following in my application.properties file.
camel.rest.data-format-property.prettyPrint=false
or not to provide that property at all.
Try this:
<removeHeaders id="removeHeaders_http*" pattern="CamelHttp*"/>
<setHeader headerName="Content-type" id="content_setHeader">
<constant>application/x-www-form-urlencoded</constant>
</setHeader>
Same with Java DSL:
.removeHeaders("CamelHttp*")
.setHeader("Content-type", constant("application/x-www-form-urlencoded"))
Hi I am new in Solr and using Solr 7.0.0 running in windows 7.
I created a collection and indexed folder with pdf and html files residing in a folder using the following command:
> java -jar -Dc=guidanceDoc -Dauto example\exampledocs\post.jar M:\Projects\guidance\documents\*
If I write a query, I get results. However, if I turn the hl=on, I get a section for highlights without any text.
Here is the query:
http://localhost:8983/solr/guidanceDoc/select?hl.fl=_text_&hl=on&%20q=_text_:"Home%20Use"
Here is the highlight part of the result:
"highlighting":{
"M:\\Projects\\g1\\documents\\gg331681":{},
"M:\\Projects\\g1\\documents\\gg209337":{},
"M:\\Projects\\g1\\documents\\ggM380327":{},
"M:\\Projects\\g1\\documents\\gg470201":{},
"M:\\Projects\\g1\\documents\\gg507278":{},
"M:\\Projects\\g1\\documents\\gg073767":{},
"M:\\Projects\\g1\\documents\\gg380325":{},
"M:\\Projects\\g1\\documents\\gg484345":{},
"M:\\Projects\\g1\\documents\\gg259760":{}}}
How can I make it work?
Your field for a highlighting should be marked as stored=true. Since you're running Solr in cloud mode, I will recommend to use Schema API to change field definition:
curl -X POST -H 'Content-type:application/json' --data-binary '{
"replace-field":{
"name":"hl_field",
"type":"text",
"stored":true }
}' http://localhost:8983/solr/guidanceDoc/schema
Using curl this can be done with: (update price field with value 100)
curl http://localhost:8983/solr/mycore/update?commit=true' -H 'Content-type:application/json' -d '[{"id":"1","price":{"set":100}}]
How to do the same using http get method? I need to fill the XXXX in the following:
http://localhost:8983/solr/mycore/update?stream.body=XXXX&commit=true
The following does not work:
http://localhost:8983/solr/mycore/update?stream.body=<add><doc><field name="id">1</field><field name="price" update="set">100</field></doc></add>&commit=true
the stream.body does not need to be xml, so this works:
http://localhost:8983/solr/mycore/update?stream.body=[{"id":"1","price":{"set":100}}]&commit=true
Solr provides way to query in JSON Format -
curl http://localhost:8983/solr/techproducts/query -d '
{
"query" : "memory",
"filter" : "inStock:true"
}'
Can I just pass this json as it is to SOLRJ Client. I need to intercept the request and pass it as it is.
SolrJ client send queries as url parameters (q=memory&fq=inStock:true) and response type is javabin https://wiki.apache.org/solr/javabin
You can use apache http client and set your JSON query and fire request to Solr.
Essentially, we can also set the parameter "json" and the query in SolrJ SolrQuery:
SolrQuery.add("json", "{json query here}")
