Boosting fields at query time in Standard Request Handler from Solrconfig.xml
Hi, I am developing a search engine app using Asp.Net, C# and Solrnet. I use the standard request handler. Is there a way I can boost the fields at query time from inside the solrconfig.xml file itself. Just like the qf field for Dismax handler. Right now am searching like field1:value^1.5 field2:value^1.2 field3:value^0.8 and this is done in the middle tier. I want Solr itself to do this using standard request handler. Can I write a similar kind of thing inside standard req handler? Here is my solrconfig file. requestHandler name=standard class=solr.SearchHandler default=true lst name=defaults str name=echoParamsexplicit/str str name=hltrue/str str name=hl.snippets3/str str name=hl.fragsize25/str str name=qffile_description^100.0 file_content^6.0 file_name^10.0 file_comments^4.0 /str /lst arr name=last-components strspellcheck/str /arr /requestHandler But am not able to see the results if I add this in my solrconfig.xml file. I have edited the post to add my req handler code in solrconfig. But, if have my query string as file_description:result^1.0 file_content:result^0.6 file_name:result^0.5 file_comments:result^0.8, am able to see the required result. Regards Vignesh
RE: problem in setting field attribute in schema.xml
It's very strange. Even I tried the same now and am getting the same result. I have set both indexed=false and stored=false. But still if I search for a keyword using my default search, I get the results in these fields as well. But if I specify field:value, it shows 0 results. Can anyone explain?

RE: problem in setting field attribute in schema.xml
I tried deleting the index and trying it again. But still I get the same result.

Solr will happily serve what's in the Lucene index even if it does not match your current schema - that's why it's important to re-index everything if you make changes to the schema and you want those changes to be visible. -- Jan Høydahl, search solution architect Cominvent AS - www.cominvent.com On 25. mai 2011, at 15.47, Vignesh Raj wrote: It's very strange.

Highlighting in solr
Hi, I use Solrnet to develop a search engine. In my application, I have a field called file_contents which I use for highlighting. Am able to get the highlights without a problem. Now I need to format it. For example, if the keyword occurs multiple times in the field, I have to display it lime what google does. May be like this. GSMArena.com: Toshiba GSM cellphones. ... Toshiba phones. Toshiba. Filters. Available . Coming soon . Smartphone . Touchscreen . Camera . Bluetooth . Wi-Fi ... Multiple snippets here are separated by I need to achieve something like this. Am able to get multiple snippets. But how do I deal with the separating? Regards Vignesh
Opening a file at a page where I encounter a hit
Hi, I am using ASP.Net MVC and solrnet for my search tool. The files I index include pdf files, word docs, excel etc... I am able to search and retrieve all the docs with a hit. Now the problem lies in opening the files with a hit. When I open the file, it should open at the location where the hit is encountered. How do i manage this? It will be even more helpful if I can highlight the hit inside the opened document? Please help me in this regard. Regards Vignesh
Lazy loading error in Extracting request handler
Hi,
I am new to Solr and its configuration. I need to index some pdf files and
for that reason I thought of using the extractingrequesthandler.
I use Apache tomcat and run solr from it.
I used the following command to index a pdf file.
C:\Users\vikky\Downloads\curl-7.21.0-win64-nosslcurl.exe
http://localhost:8983/solr/update/extract?literal.id=doc4uprefix=attr_fma
p.content=attr_contentcommit=true -F
myfile=@G:\Official\Archiving\apache-solr-1.4.1\apache-solr-1.4.1\docs\featu

But, I got the following error.
