[英]Postgres full text search on json
I am dumping a json value into text
field as I have some invalid json data that cannot be stored in json
/ jsonb
. 我将json值转储到text
字段中,因为我有一些无法存储在json
/ jsonb
无效json数据。 I would like to search and highlight "Value16": 16711680
in the following example, but I am also getting a hit on "Value20": 16711680
. 在下面的示例中,我想搜索并突出显示"Value16": 16711680
,但我也对"Value20": 16711680
。
{
"Value01": 122,
"Value02": 25,
"Value03": 9,
"Value04": 538,
"Value05": false,
"Value06": 65534,
"Value07": 2,
"Value08": 0,
"Value09": 2,
"Value10": 1,
"Value11": 0,
"Value12": 0,
"Value13": false,
"Value14": 0,
"Value15": 0,
"Value16": 16711680,
"Value17": 0,
"Value18": 0,
"Value19": 0,
"Value20": 16711680,
"Value21": 0,
"Value22": 0
}
I tried following queries but did not work. 我尝试了以下查询,但是没有用。 Do I need to use any escape characters here? 我需要在这里使用任何转义字符吗?
to_tsquery('Value16<->16711680')
to_tsquery('Value16&16711680')
Basically I would like to hit only if key and value match together . 基本上,我只想在键和值匹配时才能命中。
How to search for a key/value pair in the json text? 如何在json文本中搜索键/值对?
Since your key and value are directly adjacent, I would suggest a phrase search (requires Postgres 9.6 or later): 由于您的键和值直接相邻,因此建议您进行词组搜索 (需要Postgres 9.6或更高版本):
...
WHERE my_tsvector @@ to_tsquery('simple', 'Value16 <-> 16711680');
Or: 要么:
...
WHERE my_tsvector @@ phraseto_tsquery('simple','Value16 16711680');
Only qualifies with the two search terms next to each other (ignoring noise characters in between). 仅限定两个相邻的搜索词(忽略它们之间的噪音字符)。 There is also the <N>
variant of the operator for terms a couple of words apart. 运算符还有<N>
变体,用于分开几个单词。

You can even combine this with prefix matching: 您甚至可以将其与前缀匹配结合使用:
