I have thousands of docs in my solr instance.
The following doc (maybe others) is causing exception everytime
highlight is turned on.
<doc>
<str name="topicTitle">
Best buy - Acer Aspire AS5610-2273 - $599. Windows vista, 1 GB RAM
</str>
</doc>
The exception is like this:
java.lang.StringIndexOutOfBoundsException: String index out of range: -52

This exception only occurs when highlight is on and the above doc is in the
response.
So for example, these three requests all cause the exception:
hl=on&hl.fl=topicTitle&hl.fragsize=0&hl.simple.pre=<em>&hl.simple.post=</em>&q=topicTitle:best+buy;replies
desc&start=40&rows=10
hl=on&hl.fl=topicTitle&hl.fragsize=0&hl.simple.pre=<em>&hl.simple.post=</em>&q=topicTitle:acer;replies
desc&start=0&rows=10
hl=on&hl.fl=topicTitle&hl.fragsize=0&hl.simple.pre=<em>&hl.simple.post=</em>&q=topicTitle:vista;replies
desc&start=60&rows=10
Below is the field definition for topicTitle. What's so special about the
above doc?
<fieldtype name="text" class="solr.TextField" positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<!--in this example, we will only use synonyms at query time-->
<filter class="solr.SynonymFilterFactory"
synonyms="index_synonyms.txt" ignoreCase="true" expand="true"/>
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt"/>
