````auto
var searchResponse = elasticClient
.Search<Case>(s => s
.Index(IndexNames.Cases)
.Query(q => q
.Match(m => m
.Field("Description")
.Query(queryParameterDto.SearchString)
)
||
q.Match(m => m
.Field("Title")
.Query(queryParameterDto.SearchString)
)
&& q
.Match(m => m
.Field(f => f.Title)
.Query("Cam")

.DateRange(r => r
.Field(f => f.IncidentOn)
.GreaterThanOrEquals(new DateTime(2017, 01, 01))
.LessThan(new DateTime(2018, 01, 01))```
