How could I limit a specific field size ?

[Veselin K <ve...@campbell-lange.net>]

Hello,

I'm trying to tune my Solr installation, specifically the search
results.

At present, my search queries return some standard fields like filename,
filepath and text of the matching file.

However the text field contains the full contents of the file, which is
not very efficient in my case.

I'd like to copy the "text" field to a field called "preview" and
then limit the "preview" field to just a few lines of text (or number of
terms). 

Then I could configure retrieving the "preview" field instead of "text"
upon search.

Is there a way to specify such size limits per field or something similar?


Thank you much.

Regards,
Veselin K

Correction. Use maxChars, not maxLength.

Yes, there is a maxLength attribute for a copyField which you can use:

<copyField source="text" dest="highlight" maxLength="30000" />
