Grails searchable search BigDecimal range

Question

I have Grails project with domain that has multiple fields, among them I have field 'price'. I added searchable plugin to the project and it works fine, via general search:

def searchResults = searchableService.search(params.q, params)

Now I need to add price search via range. Example: price between $100 and $200. I tried following but it doesn't work:

def searchResults = searchableService.search({
    queryString(params.q)
    lt("price", params.pmax?.trim().toBigDecimal())
},params)

How do I implement range search? Does it matter what kind of data type it is: Integer, BigDecimal, Long?

Thank you

Answer 1

I did a search by range like this:

def searchResults = searchableService.search(params){
    must(queryString(params.q) {
        ge('price', params.pmax as BigDecimal)
        le('price', params.pmin as BigDecimal)
    })
}

[EDITED]

My previous solution doesn't work perfectly. The right way to do search with numbers with searchable, you need first add this in your domain class:

searchable {
     price index: "not_analyzed", format : "0000000000"
}

And then to do the search:

def searchResults = yourDomainClass.search("price:[" + (params.pmin ? params.pmin.trim().padLeft(10, "0") : "*"  )+ " TO " + (params.pmax ? params.pmax.trim().padLeft(10, "0") : "*"  )+ "]"

All that is need because when your data is indexed, is also textified.
