How to extract a field with a prefixed dimension?

[javozzo <da...@gmail.com>]

Hi,
i'm new in solr.
i use the content field to extract the text of solr documents, but this
field is too long. 
Is there a way to extract only a substring of this field?
i make my query in java as follow:

SolrQuery querySolr = new SolrQuery();
querySolr.setQuery("*:*");
querySolr.setRows(3);
querySolr.setParam("wt", "json");
querySolr.addField("content");
querySolr.addField("title");
querySolr.addField("url");

any ideas?
Thanks
Danilo

Not too sure what you're asking. Are you saying that you want to only
return a relevant part of a field in search results - i.e. a contextual
snippet?

If so, then you should look at the highlighting component, which can do
this.
