Search for a word NOT followed by another on a Solr query

[ivan <iv...@presstoday.com>]

What i'm trying to do is to only get results for "Leonardo" when is not
followed by "da vinci".
If i have "Leonardo da vinci" in my result is fine as long as i have another
"Leonardo" without "da vinci".

Examples:
"Leonardo foo bar"  OK
"Leonardo da vinci foo bar" KO
"Leonardo foo bar Leonardo da vinci"  OK

I can't seem to find any way to do this using solr queries, because if i do
something like -"Leonardo da vinci" i lose all results where i have both
"Leonardo" and "Leonardo da vinci". I tried using various combinations of
boolean logic but can't get it to work.

Any help?
Thanks

Hi Ivan,
You might be able to use complexphrase query parser to get what you need, you can test something like this:

{!complexphrase df=my_field}”Leonardo -(da Vinci)”

HTH,

This way i'm losing results where i have both "Leonardo" and "Leonardo da
vinci in the same field, see example number 3 "Leonardo foo bar Leonardo da
vinci".
I want this case to match and with your query i'm not getting it.
