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.
