Solr Highlighting full phrases instead of words

[Endika Posadas <en...@gmail.com>]

Hi all,

I am using Solr's Unified highlighter to highlight parts of a text block.
However, I have noticed that the highlighter, instead of highlighting the
whole phrase, highlights the words separately.

For example, if we search for "hello world" it will highlight <b>hello</b>
<b>world</b>. Both words are highlighted, so it's barely noticeable.

On the other hand, if we phrase search for "hello world" and the text
contains 'hello to the world' (where 'to' and 'the' are stop words), it
will highlight <b>hello</b> to the <b>world</b>. This can be a bit
confusing and we would like to highlight the whole phrase instead <b>hello
to the world</b>.

Is there a way to highlight so that the whole matched phrase gets
highlighted instead of the individual words?

Thanks
