Apache Solr Reference Guide Covering Apache Solr 6.0

Each non-comment, non-blank line consists of a mapping of the form: "source" => "target"
Double-quoted source string, optional whitespace, an arrow ( => ), optional whitespace,
double-quoted target string.
Trailing comments on mapping lines are not allowed.
The source string must contain at least one character, but the target string may be empty.
The following character escape sequences are recognized within source and target strings:
Escape
sequence
Resulting character ( ECMA-48 alia
s)
Unicode
character
Example mapping line
\\ \ U+005C "\\" => "/"
\" " U+0022 "\"and\"" => "'and'"
\b backspace (BS) U+0008 "\b" => " "
\t tab (HT) U+0009 "\t" => ","
\n newline (LF) U+000A "\n" => ""
\f form feed (FF) U+000C "\f" => "\n"
\r carriage return (CR) U+000D "\r" =>
"/carriage-return/"
\uXXXX
Unicode char referenced by the 4 hex
digits
U+XXXX "\uFEFF" => ""
A backslash followed by any other character is interpreted as if the character were present without
the backslash.
solr.HTMLStripCharFilterFactory
This filter creates org.apache.solr.analysis.HTMLStripCharFilter. This Char Filter strips HTML from
the input stream and passes the result to another Char Filter or a Tokenizer.
This filter:
Removes HTML/XML tags while preserving other content.
Removes attributes within tags and supports optional attribute quoting.
Removes XML processing instructions, such as:
Removes XML comments.
Removes XML elements starting with .
Removes contents of and elements.
Handles XML comments inside these elements (normal comment processing will not always work).
Replaces numeric character entities references like A or  with the corresponding character.
The terminating ';' is optional if the entity reference at the end of the input; otherwise the terminating ';' is
mandatory, to avoid false matches on something like "Alpha&Omega Corp".
Replaces all named character entity references with the corresponding character.
  is replaced with a space instead of the 0xa0 character.
Newlines are substituted for block-level elements.
sections are recognized.
Inline tags, such as , , or will be removed.
Uppercase character entities like quot, gt, lt and amp are recognized and handled as lowercase.
The input need not be an HTML document. The filter removes only constructs that look like HTML. If the
input doesn't include anything that looks like HTML, the filter won't remove any input.
