Biblio search with NOT operator

Post by romahnc » Thu Jan 28, 2010 4:23 pm

Hello,

I am using the OPS 2 in Excel. Every thing works fine so far. But now I need to seach for a title and exclude some words. For example:

ti all "bike, kid" not ti="motor" -> Does not work
ti all "bike, kid" not pd=cn -> works fine

Is the "NOT" operator not allowed whitin one field?

Please help!
Thanks

Dear User,

"NOT" is allowed:

ti all "bike, kid" not ti="motor" -> works fine

for the other please use:

ti all "bike, kid" not pn=cn

Best regards,

Hi,

ti all "word1, word2" not ta any "word3, word4" ?

Dear user,

I made similar search and it works for me:
http://ops.epo.org/3.1/rest-services/p ... bicycle%22

in your email you have "ta" instead"ti" so that might be your problem.

Kind regards,

OPS support
