Hi Devon,

Are there wildcard characters in the advanced search option in Greenstone.  I want to search for a phrase rather than one word at a time. 
 
For instance if I search for "Red Fox" and I have all the three books listed below my search is going to show me all the books when I only want the 1 book called Red Fox.  
 
Books in Library
 
Red Dog
Big Fox
Red Fox

To get the results above, I can only assume that you were inputting red fox without double quote marks before the r in red or after the x in fox.


To perform a phrase search in Greenstone you need to enclose your phrase in double quote marks.


I assume you are inputting

Red Fox     i.e. without quote marks.

what you need is

"Red Fox"

with double quote marks.


 
How can I specify in my search that Red and fox are together?   Sometimes in the past I've seen searches where you can put in wildcard characters between like ? or *.  Anything like this in Greenstone advance search pages?
 

Greenstone supports the * wildcard in mgpp and lucene, so if the indexer for your collection is set to mgpp or lucene (rather than mg), search queries such as re* or fo* would work, but dont seem to be what you are after. It looks as if simply adding double quote marks above will suffice for what you want to do.



Regards,

Richard
