If you use IndexWriter.deleteAll, and not any of the other delete by Query,
Term methods, it should be quite efficient to delete, as IndexWriter just
drops all segments.
That API is also transactional, so you could call IW.deleteAll, proceed to
reindex all your documents, and if somehow that crash
Hello,
My name is Ehson Umrani and I am currently running some experiments using
Lucene. FOr the expiraments I am running I need Lucene to run as fast as
possible. Do you have any suggestions on how to achieve speeds listed on the
nightly benchmark page. I am also using 1kb Wikipedia files and
Have you already checked
https://wiki.apache.org/lucene-java/ImproveIndexingSpeed? Often when
running such benchmarks, the bottleneck is not indexing but opening or
parsing input files, so you should review that part as well.

Hi Ehson,
Have you looked at the luceneutil source code that runs the benchmarks?
https://github.com/mikemccand/luceneutil
The sources are not super clean, but that's what's running the nightly
benchmarks, starting from src/main/perf/Indexer.java.

I am seeing serious performance differences with three slightly varied
queries:

Can anyone explain why this might be happening and any tips to optimize
it? Most queries are lightning fast, but ones like "Smith Mark D" are
taking
Hi,-
i have an indexed field having "$word1 word2" and i want to find the
docs having these two words first in my first query.
i have another indexed field but i am not searching on that second
field for this first query
which is BooleanQuery with two TermQuery's having BooleanClause.Occu
It's impossible to tell for sure from the info you provided -- attachments
are not included in messages on this mailing list - but my guess is that
when you use the QueryParser api you are getting a query that has the
benefit of text processing using an Analyzer (lower-casing and other text
transfo
My problem seems similar to this one.
i make sure index has all lower cased and TermQuery search term also
gets all lower cased.
i tokenize the search string since index uses standardtokenizer and
standardfilter and lowecasefilter and asciifoldingfilter.
My index uses standardtokenizer and
It seems in my query string i cant see $ when print it out from
MultiFieldQueryParser but the search string has $ in it and it finds hits.
On the other hand, Termquery based BooleanQuery keeps $ and no hits.
i use $ for starts with effect.
Best regards
