Full-Text search, how to mark whole phrases

Hi,

I have placed small document in database with enabled full-text index: <text> Text with hello world phrase. </text>

The following expression: ft:mark(db:open('simple')//*[text() contains text 'hello world'])

produces: <text>Text with <mark>hello</mark> <mark>world</mark> phrase.</text>

Is it possible to enclose result in one element <mark>hello world</mark> ?

Hi Bartosz,

unfortunately this is not possible, because at the stage of marking the terms, we don’t have any information if the matched terms were the result of a single or phrase search. If all of your adjacent query terms will be the result of phrase queries, you could rewrite your result with some additional XQuery code (using e.g. a transform expression [1]).

Hope this helps, Christian

In general this is not possible using XQuery and XPath Full Text 1.0, and it's the single most-requested feature for a future version.

Many vendors provide an extension to do "match highlighting" including BaseX:
