I am trying to write a little application that retrieves data by using only string matching technique.....almost always it returns a lot of junk data which are not relevant ...however it matched the search string ....similar to internet search engines......now the problem is that relevant data gets buried in too much irrelevant data and the user will need to spend too much time trying to find the relevant data..........

Can someone suggest any other way of search which is not based on pure string matching?

Any links to other web sites which deals with this subject or published papers in this subject will be highly appreciated.........

Most web search engines have the ability to search on several strings, combining them with AND, OR, NOT and () to make a more sophisticated search. You might also include a date range if this is appropriate. Another "filter" you could add would be to restrict the sites/documents that you search, so for a web engine you might automatically filter out anything from aol or hotmail.

And, ranking the result set is considered the opposite approach.

Most search engines, actually, work on a mix of the two approaches.

BTW, whichever the way, they all work based on pure string-matching... i agree with you, this is not satisfactory, but it is the "state of the art", i.e. the rest is research.
