Re: Solr GET requests return quickly, POST requests take very long, why?


hi,

You need to give us some example...while you should ask in the tomcat user
group of how tomcat/apache dealing with POST request as ryan said they go to
the same loop.

Thank you,
Vinci

stored and indexed in schema


Hi,

I would like to ask, if I set a field to be indexed but not stored, I can
retrieved the document but cannot retrieve this field?
If I have large field that I want to index but I am not suppose to show them
to user (The origin content stored in another processed document where I am
using another field in Solr to point to their location...I throw the
retrieval job to the server :P), will I get faster respond even the query
doesn't ask solr to return this large field?

Thank you,
Vinci

Re: Indexing a word in url


Hi,

Thank you for your reply.
Actually I want to use anything that is not alphabet or digit to be the
separator - anything between them will be a word (so that I can use the URL
fragment to see what is indexed about this site)...any suggestion?

Thank you,
Vinci

Re: Solved! Solr interprets UTF-8 as ISO-8859-1

That did the trick. I actually figured it out on my own 10 minutes after 
I posted to the mailinglist. Typical ;-)
Thanks for the help anyway everybody!

That's correct.  By definition :)

You'll get better response in that Solr won't be taking the time to  
retrieve the large stored field, writing it to the response, and the  
client-side parsing that data, sure.

Re: Setting a Threshold of a sortable field to filter the result?

I'll let the example schema.xml speak for itself:

     <!-- numeric field types that store and index the text
          value verbatim (and hence don't support range queries,  
since the
          lexicographic ordering isn't equal to the numeric ordering)  
-->
     <fieldType name="integer" class="solr.IntField" omitNorms="true"/>
     <fieldType name="long" class="solr.LongField" omitNorms="true"/>
     <fieldType name="float" class="solr.FloatField" omitNorms="true"/>
     <fieldType name="double" class="solr.DoubleField"  
omitNorms="true"/>

     <!-- Numeric field types that manipulate the value into
          a string value that isn't human-readable in its internal form,
          but with a lexicographic ordering the same as the numeric  
ordering,
          so that range queries work correctly. -->
     <fieldType name="sint" class="solr.SortableIntField"  
sortMissingLast="true" omitNorms="true"/>
     <fieldType name="slong" class="solr.SortableLongField"  
sortMissingLast="true" omitNorms="true"/>
     <fieldType name="sfloat" class="solr.SortableFloatField"  
sortMissingLast="true" omitNorms="true"/>
     <fieldType name="sdouble" class="solr.SortableDoubleField"  
sortMissingLast="true" omitNorms="true"/>

Re: How to handle multiple application?

You *may* want to consider MultiCore:
http://wiki.apache.org/solr/MultiCore

but it may still be more appropriate to install multiple instances.
