Hi,
I'm indexing pdf documents to use full text search with solr.
To get the number of the page where the result was found, I save every
page separately and group the results with a field called doc_id.
(See this topic:
http://mail-archives.apache.org/mod_mbox/lucene-solr-user/201303.mbox/%3c1362242815.4092.140661199082425.338ed...@webmail.messagingengine.com%3E
)
This works fine if I search in a single document, but if I search over
the whole database for a term, the results are really really slow,
especially if group.limit is above 10. I indexed about 150.000 pages
for now, but in the end it will be more than 1.000.000 pages.
How can I improve search performance?
I'm using this configuration:
<requestHandler name="/search/fulltext" class="solr.SearchHandler">
<lst name="defaults">
<str name="echoParams">explicit</str>
<str name="wt">json</str>
<str name="indent">true</str>
<str name="df">text</str>
<!-- Query settings -->
<str name="defType">edismax</str>
<str name="qf">

<str name="hl.simple.post"><![CDATA[</strong>]]></str>
</lst>
</requestHandler>
THX for your help.
