对s中的同一字段或条件使用多个值的PySolr搜索

Question

我的PySolr代码在下面

filter_queries = []
        facet_fields   = []

        for key, value in request.GET._iterlists():
            if(key != 'Rows' and key != 'Sort' and key != 'Facet' and key != 'FacetFields' ):
                filter_queries.append(key + ':' + request.GET[key])
            else:
                if(key == 'Rows'):
                    rows = request.GET['Rows']

                if(key == 'Sort'):
                    sort = request.GET['Sort']

                if(key == 'Facet'):
                    facet = request.GET['Facet']

                if(key == 'FacetFields'):
                    facet_fields = request.GET['FacetFields'].split(",")

                if(key == 'Start'):
                    start = request.GET['Start']

 params = {
            'fq': filter_queries,
            'facet': facet,
            'facet.field': facet_fields,
            'rows': rows,
            'sort': sort,
            'start':start,
        }

try:
            results = solr.search(q='*', **params)
            documents = json.dumps(results, default=lambda o: o.__dict__)
        except Exception as e:
            # handles SOLR invalid queries
            documents = json.dumps({'error': 1, 'reason': str(e)})

        return HttpResponse(documents)

当我传递?CityId = 3156它工作正常，但现在我需要为CityId传递两个值（例如solr query url?q=CityId:3156+OR+CityId:2278），如何在PySolr中实现这一点？在

Answer 1

您可以只编写查询

CityId:(3156+OR+2278)

或者，您可以正常编写查询，在params中设置q.op参数

 query = 'CityId: 3156 2278'
 params = {
        'fq': ...,
        'facet': ...,
        'facet.field':...,
        'rows': ...,
        'sort': ...,
        'start':...,
        'q.op': 'OR'
    }

Answer 2

Im对请求使用AJAX，但是在Solr的所有api中语法都是相同的。如果要对单个字段进行多个查询，则应使用括号，如下所示：

CityId:(3156+OR+2278)

这应该能解决问题。在
