Diff FieldType's encode diff values into terms in diff ways. at query time the FieldTypes need to be consulted to know how to build the resulting query object.
Solr's query parsers are "schema aware" and delegate to the appropriate FieldType to handle any index term encoding needed -- but the lower level lucene QueryParser that you ar using does not... : org.apache.lucene.search.Query query = parser.parse(solrQueryString); : : where parser is org.apache.lucene.queryparser.classic.QueryParser and then : the following is used to get the document IDs: ...for anything except trivial StrField instances, that's not going to work -- not for any Trie based fields, or any TextFields (unless you go get the Analyzer from the schema) or any non trivial FieldTypes. : The code worked perfectly in Solr 4.5. Now, in Solr 5.5.4, it works only if : the query does not contain a date range query. For example, solrQueryString: I'm not sure how that would have worked in Solr 4.5, ... unless perhaps your definition of a "date" field was different in the schema's you used in 4.5, and did not involve a Trie based date field (the very old legacy date format ields used a simple String based encoding that might have worked) The correct way for a plugin to do the sort of thing you are trying to do would be to use an instance of SolrQueryParser -- see for example the code in LuceneQParser and how it uses SolrQueryParser ... you'll most likeley just want to use LuceneQParser directly in your plugin to simplify things. -Hoss http://www.lucidworks.com/
