Subject Re: Very basic questions: Indexing text - working, but slow!
Date Tue, 29 Jun 2010 18:07:36 GMT
Thanks for everyone's help - I have this working now, but sometimes the queries are incredibly
slow!!  For example, <int name="QTime">461360</int>.  Also, I had to bump up the
min/max RAM size to 1GB/3.5GB for things to inject without throwing heap memory errors.  However,
my data set is very small!  36 text files, for a total of 113MB.  (It will grow to many TB,
but for now, this is a test).  The largest file is 34MB.

Therefore, I'm sure I'm doing something wrong :-)  Here's my config:


For the schema.xml, <types> is all default.  For fields, here are the only lines that
aren't commented out:

   <field name="id" type="string" indexed="true" stored="true" required="true" />
   <field name="body" type="text" indexed="true" stored="true" multiValued="true"/>
   <field name="timestamp" type="date" indexed="true" stored="true" default="NOW" multiValued="false"/>
   <field name="build" type="string" indexed="true" stored="true" multiValued="false"/>
   <field name="device" type="string" indexed="true" stored="true" multiValued="false"/>
   <dynamicField name="*" type="ignored" multiValued="true" />

... then, for the rest:


 <!-- field for the QueryParser to use when an explicit fieldname is absent -->

 <!-- SolrQueryParser configuration: defaultOperator="AND|OR" -->
 <solrQueryParser defaultOperator="AND"/>


Invoking:  java -Xmx3584M -Xms1024M -jar start.jar




for i in `find . -name \*.txt`; do 
	(( J++ ))
	curl "http://localhost:8983/solr/update/extract?$J&fmap.content=body" -F

echo "------------- Committing"
curl "http://localhost:8983/solr/update/extract?commit=true"
