Hi Liam,

Greenstone does support phrase searching, using quotes (") to specify the
phrase.

For example, try going to http://www.nzdl.org and clicking on the "humanity
development library" (the first collection). If you search for

snail farming

you get 47 documents matching the query. But if you search for

"snail farming"

you only get 9 documents matching the query. Greenstone searches for all
documents containing "snail" or "farming", then merges the results and
scans through each document to check for the whole phrase "snail farming".
(You should get a message at the top of the search results saying
"post-processed to find "snail farming"", which indicates this has
happened.)

Regards,

Michael
