Struct SpanFieldMaskingQuery

pub struct SpanFieldMaskingQuery { /* private fields */ }

Wrapper to allow span queries to participate in composite single-field span queries by lying about their search field. The span field masking query maps to Lucene’s SpanFieldMaskingQuery

This can be used to support queries like span-near or span-or across different fields, which is not ordinarily permitted.

Span field masking query is invaluable in conjunction with multi-fields when same content is indexed with multiple analyzers. For instance we could index a field with the standard analyzer which breaks text up into words, and again with the english analyzer which stems words into their root form.

Note: as span field masking query returns the masked field, scoring will be done using the norms of the field name supplied. This may lead to unexpected scoring behavior.
