Right - my point was to combine this with the previous approaches to
form a query like:
samsung AND android AND GPS AND word_count:3
in order to exclude documents containing additional words. This would
avoid the combinatoric explosion problem otehrs had alluded to earlier.
Of course this would fail because android is "mis-" spelled :)

I'm pretty sure the word-count strategy won't work.
If I search with the text "samsung andriod GPS", search results
should only conain "samsung", "GPS", "andriod" and "samsung andriod".
Using the word-count strategy, a document containing "samsung andriod PDQ"
would be a hit, but Varun doesn't want it, because it contains a word that is not in the
query.

You might try adding a field containing the word count and making sure
that
matches the query's word count?
This would require you to tokenize the query and document yourself,
perhaps.

Thanks everybody for the inputs.
Looks like Steven's solution is the closest one but will lead
to performance issues when the query string has many terms.
I will try to implement the two filters suggested by Steven
and see how the performance matches up.

Steve's answer
is quite near your request. You can do further work based
on his solution.
At the last step, I'll suggest you eat up all blank within query
string and query result, respevtively& only returns those results
that has equal string length as the query string's.
For example, giving:
*query string = "Samsung with GPS"
*query results:
resutl 1 = "Samsung has lots of mobile with GPS"
result 2 = "with GPS Samsng"
result 3 = "GPS mobile with vendors, such as Sony, Samsung"
they become:
*query result = "SamsungwithGPS" (length =14) *query results:
resutl 1 = "SamsunghaslotsofmobilewithGPS" (length =29) result 2 =
"withGPSSamsng" (length =14) result 3 =
"GPSmobilewithvendors,suchasSony,Samsung" (length =43)
so result 2 matches your request.
In this way, you can avoid case-sensitive,
word-order-rearrange load
of works. Furthermore, you can do refined work, such as
remove white
characters, etc.

Hi,
I have lot of small documents (each containing 1 to 15
words) indexed
in Solr. For the search query, I want the search results
to contain
only those documents that satisfy this criteria "All of
the words of
the search result document are present in the search query"
For example:
If I have the following documents indexed: "nokia n95", "GPS",
"android", "samsung", "samsung andriod", "nokia andriod",
"mobile with GPS"
If I search with the text "samsung andriod GPS", search results
should only conain "samsung", "GPS", "andriod" and
"samsung andriod".
Is there a way to do this in Solr.
