: Interesting. I wonder though if we have 4 million English documents and 250
: in Urdu, if the Urdu words would score badly when compared to ngram
: statistics for the entire corpus.
Well it doesn't have to be a strict ratio cutoff .. you could look at the
average frequency of all character...

Erik,
That was a wonderful explanation, I hope many folks in this forum will be
benefited from the explanation you have given here.
Actually I Googled and found the solution when you had earlier mentioned
that I can do a leading wildcard without hacking the code.
I found out the patch that h...

Leaving aside some historical reasons, the root of
the issue is that any search has to identify all the
terms in a field that satisfy it. Let's take a normal
non-leading wildcard case first.
Finding all the terms like 'some*' will have to
deal with many fewer terms than 's*'. Just dealing with
t...

I dont mean to turn this into a sales pitch, but there is a tool for Java app
performance management that you may find helpful. Its called New Relic
(www.newrelic.com) and the tool can be installed in 2 minutes. It can give
you very deep visibility inside Solr and other Java apps. (Full disclosur...

The fieldNorm is computed like this: fieldNorm = lengthNorm * documentBoost
* documentFieldBoosts
and the lengthNorm is: lengthNorm = 1/(numTermsInField)**.5
[note that the value is encoded as a single byte, so there is some precision
loss]
So the values are not pre-set for the lengthNorm, bu...

Eric,
Thanks a lot for your reply.
I was able to successfully hack the query parser and enabled the leading
wild card search.
As of today I hacked the code for this reason only, I am not sure how to
make the leading wild card search to work without hacking the code and this
type of search is t...

We've been thinking about running some kind of a classifier against each book
to select books with a high percentage of dirty OCR for some kind of special
processing. Haven't quite figured out a multilingual feature set yet other
than the punctuation/alphanumeric and character block ideas mentio...
