弹性搜索查询

Question

I'm having some issues with my elastic search querying. I have the following fields, patientid, patientfirstname, patientmidname, and patientlastname. I want to be able to enter in either one of those 4 fields and get matching results returned. So far my query works only if I use a patientid. If i type something like harry (firstname) or middle/last name it doesn't query it. Individual term querying works for each of them.

q = Q({"bool": { "should": [ {"term":{"patientid":text}}, {"wildcard":{"patientlastname":"*"+text+"*"}}, {"wildcard":{"patientfirstname":"*"+text+"*"}}, {"wildcard":{"patientmidname":"*"+text+"*"}} ]}})

r = Search().query(q)[0:10000]

Answer 1

the matching depends on your analyzers, what I would recommend is to just use:

Search().query('multi_match', query=text, fields=['patientid', 'patientlastname', 'patientfirstname', 'patientmidname'])

which will query across those fields (you can read about different type s of multi_match query in [0]).

You just need to make sure that all the patient name fields are properly analyzed (see [1] for details)
