I have a set of documents like
{
tags:['a','b','c']
// ... a bunch properties
}
As stated in the title: Is there a way to filter all documents containing any of given tags using Nest ?
For instance, the record above would match ['c','d']
Or should I build multiple "OR"s manually ?
There's also terms query which should save you some work. Here example from docs:
{
"terms" : {
"tags" : [ "blue", "pill" ],
"minimum_should_match" : 1
}
}
Under hood it constructs boolean should. So it's basically the same thing as above but shorter.
There's also a corresponding terms filter.
So to summarize your query could look like this:
{
"filtered": {
"query": {
"match": { "title": "hello world" }
},
"filter": {
"terms": {
"tags": ["c", "d"]
}
}
}
}
With greater number of tags this could make quite a difference in length.
