Yes alessandro,
I know  that their us some downsight of using sow =false but if don't use
it then neither shingle nor bhram will work ,and these are required in my
case/setup

Isn't this a case where you don't want the query parser to split by space
before the analyser ?
Take a look to the "sow" param for the edismax query parser.
In your case you should be ok but Be aware that is not a silver bullet for
everything and that other problems could arise in similar scenarios [1].

The *sow* Parameter
Split on whitespace: if set to false, whitespace-separated term sequences
will be provided to text analysis in one shot, enabling proper function of
analysis filters that operate over term sequences, e.g. multi-word synonyms
and shingles. Defaults to true: text analysis is invoked separately for each
individual whitespace-separated term.
