In Depth Information
will be scoped depending on where you initiate the search. If you are on a list or library,
even though the search field will say “Search this site…,” it will actually only return results
for that list or library. However, on the search result page, you can then change the scope to
“This site” (which strangely also places you one step from the site’s home page, regardless
of the list you were originally on when you first initiated the search), and it will search the
whole site for your query.
The search results are displayed on a page organized by relevance. Results are displayed
with the link to it and some summarizing information (see Figure 1.4).
In a server farm, there is usually only one Search service and one Index (content access)
vice running. However, if you have a large and busy server farm, it might be good to have a
server dedicated to searching and indexing, or you could run more than one server with the
Search service enabled. Search prefers Windows Authentication and may cause errors in an
anonymous environment (make sure the site is set to always search .aspx pages). In addition,
the Index service prefers NTLM authentication, so it can have problems accessing a web
application that requires Kerberos if it is using a nonstandard port (ports 80 and 443 are considered
standard). Search generally uses the default zone address for the web applications it indexes,
so it might be best to keep that zone’s authentication method to NTLM (and to consider using
extended web applications to host Kerberos or anonymous access).
Search does perform security trimming, which means it includes security information
when it is indexing site collections and excludes items from a query based on the
permissions of the person asking.
Sites and lists can be excluded from indexing if you’d like them to be unsearchable. This
can be useful for lists with item-level security (which can confuse security trimming), and
may cause some items to be displayed in the search results for those who can’t open them.
