>text/plain</TT

<TT
CLASS="literal"
>text/html</TT
> or <TT
CLASS="literal"
>text/xml</TT

have built-in parsers.

> -
external programs which convert documents of arbitrary types
to the above types natively supported by <SPAN
CLASS="application"

>.
</P
><P
>The <CODE
CLASS="parameter"
>from_mime</CODE
> and
<CODE
CLASS="parameter"
>to_mime</CODE
> parameters are standard mime types.
</P
><P
> <CODE
CLASS="parameter"
>to_mime</CODE

and can optionally have the <CODE
CLASS="option"
>charset=</CODE

If the <CODE
CLASS="option"
>charset=</CODE
> part is omitted,
the parser output is considered to be in
<B
CLASS="command"
><A
HREF="msearch-cmdref-localcharset.html"
>LocalCharset</A

>.
</P
><P
>By default, when executing a parser, <SPAN
CLASS="application"

> sends data
to its <TT
CLASS="filename"
>STDIN</TT

CLASS="filename"
>STDOUT</TT
>.
</P
><P
>Some parsers can not operate on <TT
CLASS="filename"

> and need a file.
The <CODE
CLASS="parameter"
>command line</CODE
> parameter can have <CODE
CLASS="varname"
>$1</CODE
>
reference which stands for a temporary file name.
If <CODE
CLASS="varname"
>$1</CODE
> is specified, <SPAN
CLASS="application"
>indexer</SPAN
> creates a temporary
file, writes the input data to it, and substitutes the temporary
file in the parser command line instead of the <CODE
CLASS="varname"
>$1</CODE
> reference.
</P
><P
><CODE
CLASS="parameter"
>Command line</CODE

for example <CODE

See the list of all available variables in <KBD

in the lines having the "<TT

</P
><P
> The fourth parameter <CODE
CLASS="parameter"
>source</CODE

It can specify what kind of data is sent to the parser.
By default, <SPAN
CLASS="application"
>indexer</SPAN
> sends raw document content.
With help of the <CODE
CLASS="parameter"
>source</CODE
> parameter you
can mix document content with other kind of data,
for example, its <ACRONYM
CLASS="acronym"
>URL</ACRONYM
> or some <ACRONYM
CLASS="acronym"
>HTTP</ACRONYM
> header,
using the same notation with the <CODE
CLASS="parameter"
>command line</CODE
> parameter.
Raw content is available as <CODE
CLASS="varname"
>${HTTP.Content}</CODE
