I admit I only skimmed your post, and at the level you're at I'm not sure
how to hook it in, but see:
https://issues.apache.org/jira/browse/SOLR-2429(SOLR-3.4) which allows
you to specify cache=false which will specifically
NOT put the filter into the filter cache at the Solr level.

Hello thank you in advance for your help!,
*Context:*
I have implemented a custom search component that receives 3 parameters
field, termValue and payloadX.
The component should search for a termValue in the requested Lucene field
and for each *termValue* to check *payloadX* in its associated payload the
information.
*Constraints:*
I don't want to disable filterCache from solconfig.xml the filterCache
class=solr.FastLRUCache since I have other searchComponents that
could use the filterCache.
I have implemented this the payload search using SpanTermQuery and
attached it to q:field=termValue
public class MySearchComponent extends XPatternsSearchComponent {
public void prepare(ResponseBuilder rb){
... rb.setQueryString(parameters.**get(CommonParams.Q)...
}
public void process(ResponseBuilder rb) {
...
SolrIndexSearcher.QueryResult queryResult = new
SolrIndexSearcher.QueryResult(**);// ??? question for help
*CustomSpanTermQuery* customFilterQuery = new CustomSpanTermQuery(field,
term, payload); //search for payloadCriteria in the payload in a specific
field for a specific term
QueryCommand queryCommand = rb.getQueryCommand().**
setFilterList(filterQuery));
rb.req.getSearcher().search(**queryResult, queryCommand);
...
}
*Issue:*
If I call the search component with field1, termValue1 and:
- *payload1*(the first search) the result from filtering it is saved
in filterCache.
- *payload2*(second time) the results from the first
search(filterCache) are returned and not a different expected result set.
Findings:
I noticed that in SolrIndexSearch, filterCache is private so I can not
change\clear it through inheritance.
Also I tried to use rb.getQueryCommand().**replaceFlags() but
SolrIndexSearch.NO_CHECK_**FILTERCACHE|NO_CHECK_QCACHE|**NO_SET_QCACHE
are not public too.
*Question*:
How to disable\clear filterCache(from SolrIndexSearcher ) *only *for a
custom search component.
Do I have other options\approaches?
Best regards,
Radu
