Subject TooManyClauses: maxClauseCount is set to 1024
Date Thu, 18 Apr 2013 11:31:01 GMT
Its quite confusing about this error.

I had a situation where i have to turn on the highlighting. In some cases
though the number of docs found for a particular query was for example say
2, the highlighting was coming only for 1. I did some checks and found that
that particular text searched was in the bigger document and was towards the
end of the document.

So i increased the hl.maxAnalyzedChar from default value of 51200 to a
bigger value say 5000000. And then it started working, i mean now the
highlighting was working properly.

Now, i have encountered one more problem with the same error.

There is a document which is returning the maxClauseCount error when i do
search on content:*. The document is quite big big in size and the
hl.maxAnalyzedChars was default i.e. 51200.

I tried decreasing that i found that the error is coming exactly at 31375
char (this is did my setting the hl.maxAnalyzedChars to 31375. it worked
fine till 31374).

Solutions are most welcome as i am in great need of this.

Sample query is as below
http://localhost:8983/solr/test/select/?q=content:* AND
obs_date:[2010-01-01T00:00:00Z%20TO%202011-12-31T23:59:59Z]&fl=content&hl=true&hl.fl=content&hl.snippets=1&hl.fragsize=1500&hl.requireFieldMatch=true&hl.alternateField=content&hl.maxAlternateFieldLength=1500&hl.maxAnalyzedChars=31375&facet.limit=200&facet.mincount=1&start=64&rows=1&sort=obs_date%20desc

Regards,
Sawan
