hello
I am awfully sorry to post this message again with the same content but with
a different title, I have done that because I found the title "how to add a
new parameter to solr request"that I have given to my last post don't
reflect really what I want to do, so I prefer posting it gain with the title
"How to modify solr results ".
Hello every body
I want to modify a little bit the behaviour of Solr and I want to know if
it is possible; Here is my problem :
I give to Solr document to index which UniqueKey Field is based on the Url
and the Time at which the croawler downloaded it so UniqueKey is a digit
obtained like that MyAlgo(Url+Time); the problem occur at searching time
solr return me the result which contain duplication it means for example the
10 first result correspond to the same web page with the same content
because in fact it is the same Url. So I want to remove this duplication,
so I want to add a parameter in the solr request for example permitdupp
which takes values (true or false ) if permitdupp= true I will let the
default Solr behaviour but if permitdupp=false I want to remouve all the
duplicative document and just to keep the recent indexed document (to get
the one recent my documents contain a date field ) .
So I want to know which is the easiest way to do this;
may be there is solr parametters I have to use (faceting???????). or
Programmatically : in that case which classes I have to modify or I have
to inherit from to develop this solution.
any suggestion is welcome. and thank you in advance.
hello every body
I want just to add this example to be more clear. I have this result from
solr.
<result name="response" numFound="7" start="0" maxScore="0.59129626">

</result>
Note that it's the same field DocUrl (http://www.sarkozy.fr) for the three
shown document above. I want to get in the result something like that.
