Speeding up RangeQueries?

ex at indexing-time so that the range queries will be substituted by simple keywords. For now, I'm interested in a possibility to speed up range queries. Does the performance of a range query depend on the length of contents in the field in question? Best, Niels -- Niels Ott Computationa

Re: Memory during Indexing

At least my index remains empty when I'm querying. If I call commit() every now and then (like every 500 documents), there are data I can query. Best Niels -- Niels Ott Computational Linguist (B.A.) http://www.drn

Hi Lucene professionals! This may sound like a dumb beginner's question, but anyways: Can Lucene run out of memory during indexing? Should I use IndexWriter.flush() or .commit(), and if so, how often? Thank you for your support. Niels -- Niels Ott Computational Linguist (B.A.)

Re: Taxonomy in Lucene

indexing synonyms using WordNet. They core of the approach is - to my understanding - to add to equip synonym Tokens with the very same positions as the "original" Tokens and add them to the TokenStream. Best, Niels -- Niels Ott Computational Linguist (B.A.) http://www.drn

Deleting from Index by URL field: is it safe?

tain whether this is safe or not: is there a chance that I delete documents I would want to keep? How does the matching exactly work. During indexing, I'm using a KeywordAnalyzer for the URL field in order to avoid tokenization. Best, Niels -- Niels Ott Computational Linguist (B.A.)
