If you search "A B" (with quotes) it is correct, but if you search only A B
(without quotes) it is not correct, because, by default the query parser
creates "OR" queries.
So searching A B you will find all documents that contains A or B, while
searching only A or only B you will normally find le
Hi,
If I search for string "A B" (i.e. A followed by a space followed by B) and I
get 20 hits, then is it correct to expect that if I search for "A" (i.e. only
A), I will get at least 20 hit or more? Similarly for if I search for B, I will
get 20 hits or more?

Shai - if you're interested in parsing Japanese, check out Kakasi. It

I haven't really been following this thread so apologies
Interesting ... I don't have access to a Japanese dictionary, so I just
extract bi-grams. But I guess that in this case, if one can access an
English dictionary (are you aware of an "open-source" one, or free one
BTW?), one can use the method you mention.
But still, doing this for every Token you

The question was, how given a string "aboutus" in a document, you can return
that document as a result to the query "about us" (note the space). So we're
mostly discussing how to detect and then break the word "aboutus" to two
words.

Just catching this thread, but if I understand what is being asked I can
share how I do multi-word phrase matching. If that's not what's wanted,
pardons!

When I'm scanning some text, I do lookups in this dictionary index using
