Can you please provide any suggestions/precautions we need to take care in
this particular scenario.
You'll probably want to send that as a POST, where the URL parameters
are in the HTTP body, not the URL. With a standard GET request, there
is no body. Like most web servers, the Jetty included with Solr has an
HTTP header size limit of 8192 bytes, which affects how large a URL you
can use. The default size limit on the request body for POST requests
is two megabytes.
Depending on which query parser it ends up using, you might also need to
increase maxBooleanClauses in all your solrconfig.xml files. If this is
a situation where it's all "OR" clauses, it's recommended to use the
terms query parser, which has a minimum Solr version requirement of
4.10. That query parser doesn't care about maxBooleanClauses. Some
later versions of Solr will automatically convert lots of OR clauses
into the type of query used by the terms parser, but I do not know which
versions do that.
Thanks,
