Options include:

"case-sensitive"

A case-sensitive match.

"case-insensitive"

A case-insensitive match.

"diacritic-sensitive"

A diacritic-sensitive match.

"diacritic-insensitive"

A diacritic-insensitive match.

"ascending"

URIs should be returned in ascending order.

"descending"

URIs should be returned in descending order.

"any"

URIs from any fragment should be included.

"document"

URIs from document fragments should be included.

"properties"

URIs from properties fragments should be included.

"locks"

URIs from locks fragments should be included.

"frequency-order"

URIs should be returned ordered by frequency.

"item-order"

URIs should be returned ordered by item.

"limit=N"

Return no more than N URIs.

"skip=N"

Skip over fragments selected by the cts:query to treat the Nth fragment as the first fragment. URIs from skipped fragments are not included. This option affects the number of fragments selected by the cts:query to calculate frequencies. Only applies when a $query parameter is specified.

"sample=N"

Return only URIs from the first N fragments after skip selected by the cts:query. This option does not affect the number of fragments selected by the cts:query to calculate frequencies. Only applies when a $query parameter is specified.

"truncate=N"

Include only URIs from the first N fragments after skip selected by the cts:query. This option also affects the number of fragments selected by the cts:query to calculate frequencies. Only applies when a $query parameter is specified.

"score-logtfidf"

Compute scores using the logtfidf method.

"score-logtf"

Compute scores using the logtf method.

"score-simple"

Compute scores using the simple method.

"score-random"

Compute scores using the random method.

"score-zero"

Compute all scores as zero.

"checked"

Word positions should be checked when resolving the query.

"unchecked"

Word positions should not be checked when resolving the query.

"too-many-positions-error"

If too much memory is needed to perform positions calculations to check whether a document matches a query, return an XDMP-TOOMANYPOSITIONS error, instead of accepting the document as a match.

"eager"

Perform most of the work concurrently before returning the first item from the indexes, and only some of the work sequentially while iterating through the rest of the items. This usually takes the shortest time for a complete item-order result or for any frequency-order result.

"lazy"

Perform only some the work concurrently before returning the first item from the indexes, and most of the work sequentially while iterating through the rest of the items. This usually takes the shortest time for a small item-order partial result.

"concurrent"

Perform the work concurrently in another thread. This is a hint to the query optimizer to help parallelize the lexicon work, allowing the calling query to continue performing other work while the lexicon processing occurs. This is especially useful in cases where multiple lexicon calls occur in the same query (for example, resolving many facets in a single query).

"map"

Return results as a JavaScript Object instead of as a ValueIterator.
