 * $cmmindf: Minimum number of documents (per shard) that need a term for it to be considered.
 * $cmmaxdf: Maximum number of documents (per shard) that have a term for it to be considered.
 * $cmmaxqt: Maximum number of terms to be considered.
 * $cmmintf: Minimum number of times the term appears in the input to doc to be considered. For small fields ($title) this value should be 1.
 * $cmminwl: Minimal length of a term to be considered. Defaults to 0.
 * $cmmaxwl: The maximum word length above which words will be ignored. Defaults to unbounded (0).
 * $cmf (comma separated list of values): These are the fields to use. Allowed fields are $title, $text, $auxtext, $opening, $headings and $all.
 * $cmuf ($true|$false): use only the field data. Defaults to $false2: the system will extract the content of the $text2 field to build the query.
 * $cmpttm: The percentage of terms to match on. Defaults to 0.3 (30 percent).
