<h2>Search</h2>

<p>
You can search for keywords, function and data names and text in help
page titles.

<p>
<b>Usage:</b> Enter a string in the text field below and hit
<code>RETURN</code>.

<form name="f"
     onSubmit="searchInIndex (document.f.SEARCHTERM.value,
                              document.f.TITLES.checked,
                              document.f.KEYWORDS.checked,
                              document.f.ALIASES.checked);
                              return false;">
<INPUT TYPE=TEXT NAME="SEARCHTERM" SIZE=20 MAXLENGTH=256 VALUE="">
<INPUT NAME="TITLES" TYPE=CHECKBOX CHECKED VALUE="1"> Help page titles
<INPUT NAME="KEYWORDS" TYPE=CHECKBOX CHECKED VALUE="1"> Keywords
<INPUT NAME="ALIASES" TYPE=CHECKBOX CHECKED VALUE="1"> Object names<br>
<INPUT VALUE="Search" TYPE=SUBMIT>
<INPUT VALUE="Reset" TYPE=RESET>
</form>

<br>

<p> For search to work, you need Java installed and both Java and
JavaScript enabled in your browser.<br> On the Mozilla/Netscape family
of browsers you should see `Applet SearchEngine started' at the left
edge of the status bar.  For help consult the
<a href="../../manual/R-admin.html#Enabling-search-in-HTML-help">R Installation and Administration</a> manual.
</p>

<p> On Mozilla-based browsers the links on the results page will
become inactive if you return to it: to work around this you can open
a link in a new tab or window.
</p>


<p> Even if this search does not work on your system, you can always use
<samp>help.search</samp> at the R prompt.
