Description
The following query works as expected (it provides a filter for high selectivity) in other words I am forcing the brightness to be < 20.
SELECT id, color, verbs, brightness
|
FROM `vector-sample`.color.rgb AS t1
|
WHERE
|
brightness < 20
|
AND SEARCH(t1, {
|
"query": { "match_none": {} },
|
"knn_operator": "and",
|
"knn": [
|
{
|
"field": "colorvect_l2",
|
"vector": [0.0, 0.0, 127.7],
|
"k": 3
|
}, {
|
"field": "colorvect_dot",
|
"vector": [0.0, 0.0, 1.0],
|
"k": 3
|
}
|
]
|
})
|
But If I add an index here I just use the index advisor
CREATE INDEX adv_brightness ON `default`:`vector-sample`.`color`.`rgb`(`brightness`)
|
And re-run the same query I get a different result.
The FTS index definition:
