I could not find the above message but using "(1+1)-2" - including the double quotes - seemed to find a message containing 184.108.40.206 of course the minus should have excluded that post. (note: I used Browse > Content > Recently Viewed)
I guess before I show escaping works, I need convince myself that the special usage is honored.
from Browse > Content > Recently Viewed:
find && dude
(the above returns two entries)
when I add the escapes only 1 result.
find \&\& dude
I was searching, for instance,
\&& echo running
posts which such characters exist, but they are not found.
How do you know any of them were/are within the search context?
Every time I use Browse > Content > All the search appears to timeout and I get a popup message indicating an error and suggesting it was my fault for logging out.
From the OTN search "find \&\& dude" (including the double quotes) returned my above post (Re: Escape character when searching not working) with both "find && dude" and "find \&\& dude" highlighted. "find && dude" returned the same as did removing the && - "find dude". Replacing && with * - "find * dude" - did not help.
I have not seen a search result highlight && by itself. It does seem to give special treatment to && but it is not obvious to me how to use that special treatment to my benefit.
Have you tried any of the examples in the docs?
If you are searching for "find \&\& dude" the search result will show similar words, like "finding"
Here a post for example that contains && and || [, etc.
So for instance, searching for "echo \&& \|| working" without the quotes finds several results, such as works, working, echo, but && and || are not included.
Or for example, simply serach for the + sign typing /+ into the search field. It finds the + sign in tags, but not in the message body. There should be plenty of posts using a + sign.
I think there is some attempt to convert/expand the search terms using synonyms.
findi returns findiing, findy, find.I, find.ls, findiings
compare searching using each of the following:
when searching for dud dude is not highlighted but duds is,
See the following (http://docs.jivesoftware.com/jive_sbs/5.0/index.jsp and search for synonyms)
"Stop Words and Synonyms
You can improve searches for people using your community by tailoring the stop words and synonym lists to best suit your needs. For example, if you realize that people will search using slang common to your industry, you could add synonyms that associate a commonly used term with slang alternatives. A software industry example could be "programmer,developer". To add synonyms, enter a pair of words separated by a comma in the Synonyms box, then click Add Synonym."
I tested the escape character in in other Jive based forums and it works as expected. For instance, https://discussions.apple.com/index.jspa, and entering \&& or \+ in the Search communities works fine. I think this is the final prove that the back slash (\) escape character in the Oracle community search is not working.
Checking the page source, the Apple discussion board seems to be based on Jive 4.5.6. I also check the Jive Community, which is apparently on 6.0.2, with the same issues as the Oracle community using 5.0.5. The editor issues are the same all version. I wonder what Jive 7 will fix or when the upgrade will happen.
