Hi,
I've been trying to figure out how to use ngrams in Lucene 4.3.0
I found some examples for earlier version but I'm still confused.
How I understand it, I should:
1. create a new analyzer which uses ngrams
2. apply it to my indexer
3. search using the same analyzer
I found in a documentation:
Usually, if a webmaster finds that your crawler has ignored their robots.txt,
they will block you machine, or maybe even your entire IP block, from accessing
their site.

hey,
can you share your benchmark and/or tell us a little more about how your

Lucene does not provide any capabilities for crawling websites. You would
have to contact the Nutch project, the ManifoldCF project, or other web
crawling projects.
As far as bypassing robots.txt, that is a very unethical thing to do. It is
rather offensive that you seem to be suggesting that
Hi..
I'm trying nutch to crawl some web-sites. Unfortunately they restricted to
crawl their web-site by writing robots.txt. By using crawl-anywhere can I
crawl any web-sites irrespective of that web-sites robots.txt??? If yes, plz
send me the materials/links to study about crawl-anywhere or else p
Also, it's in general not good to check for IR reopen on every search
request: this could be way too often if you suddenly hit high search
load, and if it's a big reopen (a large segment merge just completed)
you slow down that one unlucky search too much; it's better to have a
background thread th
The Changes and Migration Guide on
http://lucene.apache.org/core/4_3_1/ (or 4_2_x) should help. They
usually link through to JIRA pages which will have more detail.
If you want info about lower level stuff such as Codecs, try googling
"lucene codecs" or whatever it is you're interested in.

To build and run applications using lucene you need either
lucene-4.3.1.tgz or lucene-4.3.1.zip. If you're on unix you might go
for the gzipped tar file, windows users might prefer the Zip file.
