"aln_contained_by"

Match documents whose period1 is contained by value.

"aln_meets"

Match documents whose period1 meets value, i.e. period1 ends at value start.

"aln_met_by"

Match documents whose period1 meets value, i.e. period1 starts at value end.

"aln_before"

Match documents whose period1 is before value, i.e. period1 ends before value starts.

"aln_after"

Match documents whose period1 is after value, i.e. period1 starts after value ends.

"aln_starts"

Match documents whose period1 starts value, i.e. period1 starts at value start and ends before value ends.

"aln_started_by"

Match documents whose value starts period1, i.e. period1 starts at value start and ends after value ends.

"aln_finishes"

Match documents whose period1 finishes value, i.e. period1 finishes at value finish and starts after value starts.

"aln_finished_by"

Match documents whose value finishes period1, i.e. period1 finishes at value finish and starts before value starts.

"aln_overlaps"

Match documents whose period1 overlaps value, i.e. period1 starts before value start and ends before value ends but after value starts.

"aln_overlapped_by"

Match documents whose value overlaps period1, i.e. period1 starts after value start but before value ends annd ends after value ends.

"iso_contains"

Match documents whose period1 contains value in sql 2011 standard. i.e. period1 starts before or at value starts and ends before or at value ends.

"iso_overlaps"

Match documents whose period1 overlaps value in sql 2011 standard. i.e. period1 and value have common time period.

"iso_succeeds"

Match documents whose period1 succeeds value in sql 2011 standard. i.e. period1 starts at or after value ends

"iso_precedes"

Match documents whose period1 precedes value in sql 2011 standard. i.e. period1 ends at or before value ends

"iso_imm_succeeds"

Match documents whose period1 immediately succeeds value in sql 2011 standard. i.e. period1 starts at value end

"iso_imm_precedes"

Options include:

"cached"

Cache the results of this query in the list cache.

"uncached"

Do not cache the results of this query in the list cache.

"min-occurs=number"

Specifies the minimum number of occurrences required. If fewer that this number of words occur, the fragment does not match. The default is 1.

"max-occurs=number"

Specifies the maximum number of occurrences required. If more than this number of words occur, the fragment does not match. The default is unbounded.

"score-function=function"

Use the selected scoring function. The score function may be:

linear

Use a linear function of the difference between the specified query value and the matching value in the index to calculate a score for this range query.

reciprocal

Use a reciprocal function of the difference between the specified query value and the matching value in the index to calculate a score for this range query.

zero

This range query does not contribute to the score. This is the default.

"slope-factor=number"

Apply the given number as a scaling factor to the slope of the scoring function. The default is 1.0.
