I'll ask another way
If I use termsIndex. There does not appear to be a way to get a list of
terms for a document and field easily using ValueSource. Is that right?
If not, how would I go about getting a list of terms for a field in a
document? When I do fq=ids:56 it appears to work on multivalued fields. How
does it work?
Thanks.

Subject: MultiValued FC question
(I posted on solr-user by mistake)
I am working on https://issues.apache.org/jira/browse/SOLR-2155
Trying to get a list of multiValued fields from the cache
ValueSource vs = sf.getType().getValueSource(sf, fp);
DocValues llVals = vs.getValues(context, reader);
org.apache.lucene.spatial.geohash.GeoHashUtils.decode(llVals.strVal(doc));
public String strVal(int doc) {
int ord=termsIndex.getOrd(doc);
if (ord == 0) {
return null;
} else {
return termsIndex.lookup(ord, new BytesRef()).utf8ToString();
}
}
I figure the problem is that lookup only returns one. I need more than 1 I
thought ./lucene/src/java/org/apache/lucene/document/Document.java would
help me, but it didn't much. Would I want to call getFieldables(name) ? Or
would that slow down the caching? Thoughts?
1. What is termIndex ? Why does ord() matter?
2. Is there a helper for getting a multiValue field from the Field cache?
The strVal(doc) only returns one of the multiValues. Thought one of you
gurus might know the answer.
Thanks.
