Hoss Man commented on SOLR-2113:
--------------------------------
Currently, the best choices for dealing with this type of situation (generating
filter queries from facet selectsion) are either "RawQParser" or "FieldQParser"
* raw - works well for strings and text, but because it expects the input to
be the completley raw term value, it doesn't work for FieldTypes that use
encoding in their toInternal/toExternal methods (ie: SortableIntField,
TrieIntField, etc...)
* field - handles the toInternal problem (by delegating to
FieldType.getFieldQuery()) but in the case of TextField this results in
analysis being used on the input first -- if the analyzer configured isn't
idempotent (love learning new words from yonik) this can also cause a problem
(this situation may not be common, but it can be easy to get into w/o knowing
it depending on how charfilters / stemmers are used)
Hence the desire for a new QParser ("term" seems like an appropriate name) that
can be used like the "field" or "raw" QParsers (take a field name as a
localParam) and is essentially implemented as...
{code}
return new TermQuery(new Term(fieldName,
getSchema().getField(fieldName).getType().toInternal(q)))
{code}
> Create TermsQParser that deals with toInternal() conversion of external terms
