Grails如何进行多个搜索查询

Question

I have this from my controller:

def purchaseRequestList = PurchaseRequest.createCriteria().list (params) {      
    if ( params.query) {        
        ilike('requestBy', "%${params.query}%")     
    }

Above is a snippet from my list method

It can only do one search by the params requestBy

Then i do this in my gsp

<g:form action="listPurchaseRequest" method="GET">
    <g:textField id="search" class="pull-right" name="query" value="${params.query}" placeholder=" Search"/>
</g:form>

Now i added a new param of requestNumber

How do i do two or more searches?

Answer 1

I'll take a guess that you want to use the single param query to search against multiple fields in the domain class PurchaseRequest . This could be done like:

def purchaseRequestList = PurchaseRequest.findAllByRequestByLikeOrRequestNumberLike("%${params.query}%", "%${params.query}%", params)

See the Dynamic Finders section of the Grails docs .

Answer 2

The other alternative could be nesting ilike for different params of the model using or{}:

def users = User.createCriteria().list(params) {
        if (params.query) {
            or {
                ilike("fullName", "%${params.query}%")
                ilike("email", "%${params.query}%")
            }
        }
