Re: scoring individual values in a multivalued field

[ayyanar <ay...@aspiresys.com>]

Hi Hossman, you suggested two solutions. Can you explain little bit more on
the second option? Iam not able to understand.  Kindly explain with an
example

At the moment, the simplest mechanisms for achieving something like what 
you are describing that i know of are: 
  1) repetitive values.  Add a value twice to make it counnt (roughly) 
     twice as much. (eliminating lengthNorm and customing your Similarity 
     is neccessary to make it worth exactly twice as much) 
  2) differnet fields.  Partition the spectrum of "importance" for your 
     values into N buckets, make a field for each bucket, put the value in 
     the bucket that makes the most sense, and at query time query ofr 
     each bucket with a differnet query time boost.

You make a field called "text" and you make a field called 
"important_text" and you make a field called "really_important_text". you 
index everything in the "text" field, you also index more important words 
in the "important_text" field, and you index the *really* important stuff 
in the all three fields.  At query time you search all of the fields for 
your word, and you use a higher boost value on the two important fields.
