Adding Excerpts to Solr Search Results - Including attachments

First off I’m going to address the question ‘ How to Add Excerpts to the Solr Search API ‘ .

This is worthy of note as the obvious way is to do it through the Search API UI; when in fact this method needs to be disabled and instead edited on the Solr Server Settings ‘ Still within Search API setting ‘ 

Step-by-step guide

1. Check the following is disabled.

> admin > configuration > filters > under ‘Processors

> check that ‘Highlighting’ is unticked

>  SAVE SETTINGS

 > admin > configuration > 'Your Server' > edit

2. 

> under 'Advanced' > tick 'Return an excerpt for all results.'

> 'Save settings’

3. Then in your view for the search you have add ‘Search: Excerpt’  Field.
