FAQ
Hmm, this strikes me as there being something wrong with the index,
but it could be a bug, too. Do you get an error if you just run the
BooleanQuery without the filter? How about if you run a simple
TermQuery with the Filter? Can you open the index with Luke? Does
the CheckIndex tool (in Lucene) provide any useful information? Also,
what version of Lucene are you using?

I am having some strange behavior and want to rule out that the
query that I
am constructing is the correct way to deal with this type of
query. This
is what I am working with:

I am creating a query that contains 3 different fields
Field 1: value - String
Field 2: type - String
Field 3: time - Unfortunately Strings

The query will always contain the date range. The query can contain
all 3
fields or at least 1 and 3.
i.e
1 & 2 & 3
1 & 3


I tried creating a BooleanQuery similiar to
BooleanQuery bq = new BooleanQuery();
bq.add(new TermQuery(new Term("value",
"hello")),BooleanClause.Occur.MUST);
bq.add(new TermQuery(new
Term("type","email")),BooleanClause.Occur.MUST);

parallelSearcher.search(bq, new RangeFilter("time", startTime,
endTime,true,true),col);

TopDoccollector col = new TopDocCollector(1000);
ParallelMultiSearcher parallelSearcher = new
ParallelMultiSearcher(indexes); // 1 to many indexes

//Now I add the date range
parallelSearcher.search(bq, new RangeFilter("time", startTime,
endTime,true,true),col);


The problem is when there are no matches for the boolean part of the
query... I get an input/output error...
