The way that the QueryParser configuration is initialized results in duplicate
search field aliases being defined, which in turn can cause problems with
Boolean searches.

For example, consider the following search:

kw:history && earth

This will retrieve all records that have both 'history' and 'earth' as
keywords.

Depending on your search settings, this search is received by Zebra as

@attrset Bib-1 @and @attr 4=6 @attr 5=1 @attr 1=1016 history @attr 4=6 @attr
5=1 @attr 1=1016 earth

Now consider this search, which should be identical:

kw:history && kw:earth

This search retrieves all records containing 'history', but ignores 'earth'. 
The search received by Zebra is:

@attrset Bib-1 @attr 4=6 @attr 5=1 @attr 1=1016 histor
