Re: [basex-talk] How to use ft:search() for querying 2 or more phrases?

Hi Team,

The first example mentioned here ( http://docs.basex.org/wiki/Full-Text_Module#ft:search ) is -

ft:search("db", ("A", "B"), map { "mode": "all words", "distance": { "max": "5", "unit": "words" } })

If I modify this to my requirement it will be - ft:search("db", ("A", "B"), map {"mode": "phrase"})

To me this means that, above will search nodes containing, phrase "A" and "B" both.

So my query then will be -

for $x in ft:search("Articles", ("electromagnetic waves", "electromagnetic particles"), map { 'mode':='phrase' })/ancestor::Doc return $x

But when I execute this, I get 0 result, even though, I had 5 articles. Am I wrong ? As suggested by Fabrice, intersect results in 5.

Dear John

Maybe you should add the following option :

map { 'mode':'all' }

because ’any’ is the default.

Best regards,

Fabrice

Hi Christian,

Thanks for the reply.

Using intersect, results in 5 Articles. Whereas you suggestion with -

ft:search("Articles", ("electromagnetic waves", "electromagnetic particles") )/ancestor::Doc

results in 218 Articles.

Why the difference of 213 ?

I am checking some of these additional, do they have both phrases. Will come back again.

Hi John,

You can specify more than one search string with ft:search [2]:

ft:search("Articles", ("electromagnetic waves", "electromagnetic particles") )/ancestor::Doc

In your case, the "phrase" option is not required, because it creates a single string from all of your search strings. Please see [1] for more information on the search modes.

Best, Christian

Hi BaseX Team,

The subject itself is explanatory. I have following query -

ft:search("Articles", ("electromagnetic waves"), map { 'mode':='Phrase' })/ancestor::Doc return $x

This query searches for "electromagnetic waves" as a phrase. I want to search another phrase "electromagnetic particles" with the previous

phrase.

...

List only those Articles having both these phrases.
