I have a list of synoynms which is being expanded at query time. This yields
a lot of results (in millions). My use-case is name search.
I want to sort the results by Levenstein Distance. I know this can be done
with strdist function. But sorting being inefficient and Solr function
adding to its
Here is the usecase:
I am using synonym expansion at query time to get results. this is
essentially a name search, so a search for Jim may be expanded at query time
for James, Jung, Jimmy, etc.
So ranking fields like TF, IDF, Norms do not mean anything to me. I just
reset them to zero. so all the

is there any other option to sorting. I mean, sorting can affect query
performance. Is there a way to embed this into Solr and not have a toll on
the system,
I tried boosting the scores based on strdist, but that seems to bring in
more results than expected.

Hi,
Can anyone explain me the basic pros and cons between textfield and
strfield. I am trying to use Levenstein distance on textfield, but it seems
that it can only be applied on the strfield. So my question is whats the
difference between the 2 and what are the radical advantages of one over
Well the I do not have phrases for synonym expansion. So it does work well.
The synonym expansion is done at query time. And since i am just searching
against the first name field, tf, idf and other ranking parameters do not
make sense, hence their weight has been initialized to 1. So after
I cannot move from textfield to strfield, since I am using synonym expansion.
Is there anything we can do on textfield itself

I was wondering if there is any solution for this.
Currently I expand my results to match the synonyms at query time.
So if I entered James, I would get results for Jim, Gomes, Game etc as they
would be expanded by matching the synonyms for James. But then since this is
just a one word match, tf,
Hi Lori,
Yeah. I thought exactly of the same solution. Use a copy field and boost
the relevancy of the the exact match. But my question is more broad here.
For eg, if i have a synonym for James as Jim, Games, Jimmy, Jameson
And if I normalize the tf, norm, etc factors to 1, on searching for
Wait, I thought the fuzzy match is invoked with a ~. I am not invoking any ~
but expanding my query terms with the synonyms at query time. So from what I
understarnd, when I query for James, internally, Solr would expand using
synonym search to James, Jim, Games, Jameson. So I guess, the original
Consider a db of just names. Now if I use synonym expansion at query time, I
get a set of results.
(Background: I created a class, which resets idf, tf, .. .all to 1) since
they dont matter to me anymore. What really matters is, how closely does the
query match to the given name.
Currently I am
