\label{Search_Basic}
\index{search repository, basic}
The Basic search page allows you to specify a phrase or
expression to search for in the LON-CAPA resource repository.  Search
strings can contain quoted phrases, multiple words, '-' (meaning
``not''), and multiple words or phrases joined with 'or'.  For
example:

\begin{itemize}
\item \textbf{cat} Matches resources about cats.
\item \textbf{cat or dog} Matches resources about cats or dogs.
\item \textbf{cat dog} Matches resources about both ``cat'' and ``dog''.
\item \textbf{``fluffy cat'' -dog} Matches resources on the phrase ``fluffy cat'' that do not contain ``dog''.
\end{itemize}

There are two checkboxes on the basic search page.  The first allows
you to limit your search to the domain of the machine you are
currently logged into.  The second causes a thesaurus lookup of your search phrase.  Search results will include resources
which match any of the related phrases as well as the original phrase.

The resource metadata fields searched in a basic search are listed
below.  It is worth noting that the data searched are self-reported by
the resource author.  In many cases, authors are unable to provide
relevant values for the fields searched.  If you need to search based
on properties other than the following, use the \ref{Search_Advanced}
Advanced Search link on the basic search page.

\begin{itemize}
\item title
\item author
\item subject
\item notes
\item abstract
\item keywords
\end{itemize}
