Question

I have indexed very large documents, In some cases these documents has 100.000 characters. Is there a way to return a portion of the documents (lets say the 300 first characters) when i am querying “Solr”?. Is there any attribute to set in the schema.xml or solrconfig.xml to achieve this?
I have tried many things but nothing worked.

Thank you in advance,

Tom

If you want a preview, you need to use a copyField and specify maxChars:

<copyField source="searchedField" dest="previewField" maxChars="300" />

Then display previewField instead of searchedField in your results.

I’m assuming you do not want normal search highlighting. If you do, just use the built-in highlighting parameters with hl.fragsize as outlined in this answer.
