> allow timeAllowed and cursorMark parameters
> -------------------------------------------
>
> Key: SOLR-14413
> URL: https://issues.apache.org/jira/browse/SOLR-14413
> Project: Solr
> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public)
> Components: search
> Reporter: John Gallagher
> Priority: Minor
> Attachments: SOLR-14413.patch
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Ever since cursorMarks were introduced in SOLR-5463 in 2014, cursorMark and
> timeAllowed parameters were not allowed in combination ("Can not search using
> both cursorMark and timeAllowed")
> , from [QueryComponent.java|#L359]]:
>
> {code:java}
>
> if (null != rb.getCursorMark() && 0 < timeAllowed) {
> // fundamentally incompatible
> throw new SolrException(SolrException.ErrorCode.BAD_REQUEST, "Can not
> search using both " + CursorMarkParams.CURSOR_MARK_PARAM + " and " +
> CommonParams.TIME_ALLOWED);
> } {code}
> While theoretically impure to use them in combination, it is often desirable
> to support cursormarks-style deep paging and attempt to protect Solr nodes
> from runaway queries using timeAllowed, in the hopes that most of the time,
> the query completes in the allotted time, and there is no conflict.
>
> However if the query takes too long, it may be preferable to end the query
> and protect the Solr node and provide the user with a somewhat inaccurate
> sorted list. As noted in SOLR-6930, SOLR-5986 and others, timeAllowed is
> frequently used to prevent runaway load. In fact, cursorMark and
> shards.tolerant are allowed in combination, so any argument in favor of
> purity would be a bit muddied in my opinion.
>
> This was discussed once in the mailing list that I can find:
> [https://mail-archives.apache.org/mod_mbox/lucene-solr-user/201506.mbox/%3c5591740b.4080...@elyograg.org%3E]
> It did not look like there was strong support for preventing the combination.
>
> I have tested cursorMark and timeAllowed combination together, and even when
> partial results are returned because the timeAllowed is exceeded, the
> cursorMark response value is still valid and reasonable.
