Lucene searches for two keywords separated by dash return no result

[vsinceac]

Found this for GN 2.6.4, I did not try other releases.

Example found on the fao geonetwork (also 2.6.4): ​http://www.fao.org/geonetwork/srv/en/main.home

There is one metadata containing "WOFOST-based" in Abstract. Here below some simple searches by keywords (with or wihtout "", as result is the same) for region=any, and the corresponding result:

"WOFOST based" -> OK (1) "WOFOST-based" -> NOK (0) "WOFOST?based" -> NOK (0) "WOFOST*based" -> NOK (0) "WOFOST/based" -> OK (1) "WOFOST - based" -> OK (1) "WOFOST ?based" -> NOK (0) "WOFOST? based" -> NOK (0)

Is this the expected behavior? Should I clean the keywords list for "-" (and other chars?) before sending the get query?

On the same geonetwork, both searches "November 2003 - June 2004" and "November 2003 June 2004" return the same results (containing "November 2003 - June 2004" in Abstract).

Thanks,

Victor
