Search API with keys also in OR

[filgiuff]

I used the API /api/v1/client/search with a payload like the following:

{
	"filters": [{
		"field": "ALL",
		"value": "key1 key2"
	}],
	"live": false,
	"sort": {
		"field": "title",
		"mode": "asc"
	},
	"rows": "1000",
	"start": "0",
	"nodes": [92],
	"euroVocFilter": {
		"euroVoc": false,
		"sourceLanguage": "",
		"targetLanguages": []
	}
}

Currently the search on key1 and key2 is always done in AND, reducing the number of results.

The API should give the possibility to search also with keys in OR.

We are analysing which is the best way to manage the search parameters. A solution will be provided in the next release.
