I am trying to construct, via individual query api, a query to search for
documents with a field name of "Category" and a value of either "Category1"
OR "Category2" (or both).
My code to do this (given categories is the set of strings with the category
names I wish to search for) is as follows
BooleanQuery query = new BooleanQuery();
if (categories != null && !categories.isEmpty()) {
for (String category : categories) {
TermQuery t =new TermQuery(new
Term("Category",category));
query.add(t,false,false); //Saywould like that
category
}
}
I have three documents in the index
Document 1 has zero fields called "Category"
Document 2 has one keyword field called "Category" with value "Category1"
Document 3 has two keyword fields called "Category", one with a value of
"Category1" and the other with a value of "Category2"
When I run a search with the above query, I get only one hit instead of the
expected 2. (Hits.length()=1)
Worse than that, when I attempt to access Hits.doc(0) I am getting an
immediate IOException with the message "Bad file descriptor". I think this
must be because by that time I have closed the indexSearcher (and therefore
the Reader that sat behind it). Its not clear to me how hits are associated
with a reader. Is it possible to close the reader and then re-open it later
to access a document with the hit?
