Hello,
I'm creating queries in our software, and I came across following issues:
1) The java 2.3.2 query interface contains a method
public void extractTerms(Set terms)
which is missing in the current version of CLucene. I think that it would be
very useful
while creating MultiPraseQueries based on wildcard queries, range queries or
other subqueries
that produce more than one Term (some of our stemmer may produce more than
one stem, searching
for thesaurus similar etc.)
Is anybody working on this functionality?
2) We would also need the span queries - so, same question arises - is anybody
working on this functionality?
3) I looked over the MultiPhraseQuery very shortly and I just came across this
piece of code, that seems
to me to be strange (But I haven't not test it yet). On the 5. line you call
++j, bud this index is being
increased on the line 3 too - it this really intended that you free only
every second Term?
MultiPhraseQuery::~MultiPhraseQuery(){
for (size_t i = 0; i < termArrays->size(); i++){
for ( size_t j=0;j<termArrays->at(i)->length;j++ ) {
_CLLDECDELETE(termArrays->at(i)->values[j]);
++j;
}
_CLDELETE(termArrays->at(i));
}
_CLLDELETE(termArrays);
_CLLDELETE(positions);
_CLDELETE_CARRAY(field);
}
4) Last question - is there any CL_NS(util)::BaseArray implementation for
refcounted objects?
Btw. the Array implementation does hardly allow reusing already allocated
arrays.

Subject: [CLucene-dev] Exception during thread finish
I run the IndexSearcher::_search method from separate thread (different from
thread where IndexSearcher is created and deleted).
When the thread finishes, I get exceptionin mutex_thread::lock() The reason is
_internal is already deleted (contains 0xdddddddd).
Any idea what could be wrong?
