Field is indexed as Keyword, I was using StandardAnalyzer(), but
currently I try to send queries directly via API, so I use this code
for doing job:
PrefixQuery query1 = null;
if(cat!=""){
Term term = new Term("category",cat);
query1 = new PrefixQuery(term);
Hits hits = is.search(query1);
}
Variable cat takes path like strings as arguments so eg it gets:
Top/World/Poland/
which is translated into: category:Top/World/Poland/*
Everything started to work, but I get such Exception:
org.apache.lucene.search.BooleanQuery$TooManyClauses
org.apache.lucene.search.BooleanQuery.add(BooleanQuery.java:79)
org.apache.lucene.search.BooleanQuery.add(BooleanQuery.java:71)
org.apache.lucene.search.PrefixQuery.rewrite(PrefixQuery.java:50)
org.apache.lucene.search.IndexSearcher.rewrite(IndexSearcher.java:166)
org.apache.lucene.search.Query.weight(Query.java:84)
org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:85)
org.apache.lucene.search.Hits.getMoreDocs(Hits.java:64)
org.apache.lucene.search.Hits.<init>(Hits.java:43)
org.apache.lucene.search.Searcher.search(Searcher.java:33)
org.apache.lucene.search.Searcher.search(Searcher.java:27)
when I cut the path, so in other words - I don't get exception when
query is Top/World/Poland/ but I start to get them when query is
Top/World/. I have also getMaxClauseCount() = 1024.
Lucene probably try to find all keywords which are good for
Top/World/* and put them in boolean query, am I right? If yes, I have
problem because from root category there are about 3-4kk children
categories, which I also want to search (and show category as url, so
user could get deeper in category tree if he wants).
What can I do with this, besides set up higher values in maxClauseCount?
