We have a scenario where we have to do range query with "OR" condition. It is working fine, with one query, but getting error while triggering with multiple query.
POST _scripts/dateTemplate
{
"script": {
"lang": "mustache",
"source": """
{
"query": {
"bool": {
"must": {
"query_string": {
"query": "title:({{searchkeyword}})"
}
},
"filter": {
"bool":{
"must":[
{
"match_all": {}
}
{{#f_url}} , {
"terms" : {
"f_url": [{{#toJson}}f_url{{/toJson}} ]
}
}
{{/f_url}}
],
"should":[
{{#since}}
{
"range": {
"{{since}}": {
{{#from}}"from": "{{from}}"{{#to}},{{/to}}{{/from}}
{{#to}}"to":"{{to}}"{{/to}}
}
}
}
{{/since}}
]
}
}
}
}
}
"""
}
}

Same if I add it in must clause, it is working perfectly with "AND" condition. Can you please help in framing the template with both "AND" and "OR" Condition?
回答1:
You're almost there, you simply need to let mustache know when the last element of the array is reached. So your template should look like this (i.e. we add a comma after each element, except the last one):
...
"should":[
{{#since}}
{
"range": {
"{{since}}": {
{{#from}}"from": "{{from}}"{{#to}},{{/to}}{{/from}}
{{#to}}"to":"{{to}}"{{/to}}
}
}
}{{^last}},{{/last}} <-- modify this line
{{/since}}
]
...
And then simply modify your call to include the last flag to the last element of the since array:
POST _search/template
{
"id": "dateTemplate",
"params": {
"searchkeyword": "*",
"since":[ {
"since":"@timestamp",
"from": "2018-06-01"
},
{
"since":"@timestamp",
"from": "2018-06-08",
"last": true <-- add this line
}
]
}
}
