cts.lsqtQuery(
   temporal-collection as String,
   [timestamp as Date?],
   [options as String[]],
   [weight as Number?]
) as cts.lsqtQuery

Summary

Returns only documents before LSQT or a timestamp before LSQT for stable query results.

Parameters
temporal-collection The name of the temporal collection.
timestamp Return only temporal documents with a system start time less than or equal to this value. Default is temporal:get-lsqt($temporal-collection). Timestamps larger than LSQT are rejected.
options Options to this query. The default is ().

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.
"cached-incremental"
Break down the query into sub-queries and then cache each one of them for better performance. This is enabled, by default.
"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.
weight A weight for this query. Higher weights move search results up in the relevance order. The default is 1.0. The weight should be between 64 and -16. Weights greater than 64 will have the same effect as a weight of 64. Weights less than the absolute value of 0.0625 (between -0.0625 and 0.0625) are rounded to 0, which means that they do not contribute to the score.

Example

  cts.lsqtQuery("temporal", null, "cached-incremental", xs.double("3.13"));
