[英]Elasticsearch: filter by any field
I am playing with filters in elasticsearch (we use old version 1.3.1), and I need to filter my search results by any field. 我在Elasticsearch中使用过滤器(我们使用旧版本1.3.1),并且需要按任何字段过滤搜索结果。 With query, this can be done like this: 使用查询,可以这样完成:
"query": {
"query_string": {
"query": "_all:test"
}
}
But filters seems to not work with _all statement. 但是过滤器似乎不适用于_all语句。 What can I do? 我能做什么? Would newer elasticsearch version solve my problem? 较新的elasticsearch版本可以解决我的问题吗?
Thanks in advance! 提前致谢!
PS: I need to search exact values, so I cannot use queries. PS:我需要搜索确切的值,所以我不能使用查询。 There is difference between queries and filters - if you search for my brown
, then you can expect results like: 查询和过滤器之间有区别-如果您搜索my brown
,那么您可以期望得到类似以下结果:
my brown
This is my brown dog.
someone stolen my brown wallet
But filter will return only my brown
, and that is what I need. 但是filter只返回my brown
,这就是我所需要的。
You might want to read up a little on the distinction between queries and filters . 您可能需要稍微了解一下查询和过滤器之间的区别。 What you're doing there is a query string query . 您在执行的操作是查询字符串query 。
If you do actually want to filter against exact text tokens (read up on analysis if you don't know what I mean by "tokens"), AND you have your mapping set up such that the "_all"
field behaves as you're expecting then try something like this: 如果您确实想过滤确切的文本标记(如果您不了解“标记”的含义,请"_all"
阅读分析 ),然后设置映射,使"_all"
字段的行为与您期待然后尝试这样的事情:
POST /test_index/_search
{
"query": {
"filtered": {
"filter": {
"term": {
"_all": "test"
}
}
}
}
}
If, on the other hand, you want to allow some analysis (so that "Test"
is tokenized to "test"
, for example), you may want this instead: 另一方面,如果您希望进行某些分析(例如,将"Test"
标记为"test"
),则可能需要这样做:
POST /test_index/_search
{
"query": {
"match": {
"_all": "Test"
}
}
}
Here is some code I used to play around with it: 这是我以前玩过的一些代码:
