Fuzzy Logic Implementation

[kumar <pa...@gmail.com>]

Hi 


I have a situation that if a user has to spelt wrongly then also it has to
dispaly the results. 

i am using my query in the following way 

http://localhost:2012/solr/suggest?s=royal+enifld+bike&s1=royal~0.7+enifld~0.7+bike~0.7

first it has to check with "s"----if exact results are not found then it has
to check fuzzy logic with s1. 

Here "s" is working fine without spell mistake, i am getting excellent
results. but when i use fuzzy it is not showing exact results. 

Can anyone help me how to solve this problem. 


Regards, 
Kumar

Hi

I have 4-different scenarios to get the results as per my requirement. i am
using custom request handlers in the following way.


<requestHandler name="/suggest"
class="com.abc.solr.handler.MySearchHandler">
<arr name="components">
   <str>query</str>

</lst>
</requestHandler>



can you please give me some idea how to configure spell check for the above
configuration.

Use the spell check component with collation..

Example:

http://localhost:8983/solr/spell?q=delll
ultrashar&spellcheck=true&spellcheck.extendedResults=true&spellcheck.collate=true

http://wiki.apache.org/solr/SpellCheckComponent
