document ids in "cached" in Hits and index merge

Hi, I have a stupid question regarding the transient nature of the document ids. As I understand, documents will obtain new doc ids during the index merge. Suppose if you do a search and got the Hits object. When you iterate through the documents by id, the index merge happens. How the merge and

Re: Span query performance issue

Hi, I think Span query in general should do more work than simple Phrase query. Phrase query, in its simplest form, should just try to find all terms that are adjacent to each other. Meanwhile, Span query does not necessary be adjacent to each other, but, with other words in between. Therefore, I

issues building a large index

Span query performance issue

Hi, I'm comparing SpanNearQuery to PhraseQuery results and noticing about an 8x difference on Linux. Is a SpanNearQuery doing 8x as much work? I'm considering diving into the code if the results sounds unusual to people. But if its really doing that much more work, I won't spend time optimiz

Alternate Lucene Query Highlighter

I created a lucene query highlighter (borrowing some code from the one in the sandbox) that my company is using. It better handles phrase queries, doesn't break HTML entities, and has the ability to either highlight terms in an entire document or to highlight fragments from the document. I would

Lucene uses a lock file to prevent simultaneous writes to index. You can just delete the file at C:\DOCUME~1\tom\LOCALS~1\Temp\Lucene-81022e186820264e5b78801c219b8e8b-commit.lock and be on your way. avrootshell wrote: Hi, I'm using using lucene for full text search. It worked gr8. But now
