Subject Snippet count increasing in solr causes Exception in connection with search using asterisk in query
Date Wed, 06 Mar 2013 08:29:05 GMT
in last days i made my first steps with solr 4.1.0. So far i had have no
problems and could always find a solution, mainly on this great platform.

I am using the example configuration from solr with my own fields. I am
indexing files with tika and add extra fields to the documents.

My Problem is the highlighting: per default solr returns in highlighting (if
enabled) only one hit. I would like to have them all (-1 doesn't work like
in maxAnalyzedChars, so i use 9999 instead) .
Hi Solr Users,

in last days i made my first steps with solr 4.1.0. So far i had have no
problems and could always find a solution.

I am using the example configuration from solr with my own fields. I am
indexing files with tika and add extra fields to the documents.

My Problem is the highlighting: per default solr returns in highlighting (if
enabled) only one hit. I would like to have them all (-1 doesn't work like
in maxAnalyzedChars, so i use 9999 instead) .

I've changed (added) following defaults:

<int name="f.text.hl.maxAnalyzedChars">-1</int>
<str name="f.text.hl.snippets">9999</str>
in solrconfig.xml at:

<requestHandler name="/select"
class="solr.SearchHandler">...</requestHandler>
Now if i search with placeholders like '*' i.e. "wordtofind*", the solr
server throws following exception:
