[LON-CAPA-dev] Searching

Hi Robley, 

The currently active role you have selected should not make a difference to 
the results of a search. The determinant of whether searching is allowed is 
simply that the "Browse Resources" privilege applies to your currently 
selected role.  In the case of "no role" selected, the privileges that apply 
will be "cumulative" privileges.  In such a case if the role is an advanced 
role, then you will have the ability to browse resources, so you could carry 
out a search.  Note, however, that with no role selected the SRCH button 
does not appear, although the search page can be displayed by entering the 
URL: http://s10.lite.msu.edu/adm/searchcat 

Different numbers of results are being displayed for the same search (with 
no change in role) because in some instances the search utility does not 
appear to be checking the complete list of possible domains.  For example, 
for the simple search on the word "algebra" when logged into 
s10.lite.msu.edu, total numbers of results returned varied as follows: 

390 (search stops after domain fsuK12 and before domain msu)
954 (search stops after domain msul1 and before domain ohiou)
1400 (search stops after domain ohiou and before domain physnet)
1757 (search stops after domain physnet and before domain snt)
2675 search explores all domains. 

It appears that the search is stopping prematurely at different points as it 
progresses through the alphabetized list of domains in the cluster.  I will 
be examining the lonsearchcat.pm code to investigate this problem further.
