Unable to search unrecognizable DateTime format in Jira Lucene index

Tormod Haugene

I am trying to perform a date range search directly on the Lucene index generated by Atlassian Jira. Following this guide, I hva ended up building my query in the following manner:

Which gives the Lucene query:

<span>customfield_10106</span><span>:[</span><span>2010</span><span>-</span><span>01</span><span>-</span><span>10</span><span>-</span><span>00</span><span>-</span><span>00</span><span>-</span><span>00</span><span> TO </span><span>2020</span><span>-</span><span>12</span><span>-</span><span>10</span><span>-</span><span>00</span><span>-</span><span>00</span><span>-</span><span>00</span><span>]</span>

However, this search yields no results, due the format DateTime values stored in the Lucene index.

How should I write my query to search these encoded dates?

Examples of indexed data:

The DateTime values are stored as shown in the following picture from Luke:

Here is what the first result looks like from the IntelliJ debugger:

JIRA stores dates in Lucene as the number of seconds since the Epoch (1 January 1970) in Lucene long prefix-coded format.

When viewing these values in Luke, use the 'Long (prefix-coded)' option under 'Show content as:' to show this value:

Programatically, using the JIRA API, you can use LuceneUtils.dateToString() or stringToDate() to go the other way. Or using the Lucene API, you can interpret the string value as a number of seconds by using NumericUtils.prefixCodedToLong() or longToPrefixCoded().

Try making a TermRangeQuery with lowerTerm and upperTerm filled in using LuceneUtils.dateToString().

Thank you for the thorough explanation! Using the LuceneUtils.dateToString(someDate) worked like a charm. Thanks! :-)

For future reference, here how I ended up making the range query. Thanks to Peter!

private Query getSampleRangeQuery() {
Date lower = new GregorianCalendar(2017, Calendar.AUGUST, 1).getTime();
Date upper = new GregorianCalendar(2017, Calendar.SEPTEMBER, 31).getTime();
return new TermRangeQuery("customfield_10106", LuceneUtils.dateToString(lower), LuceneUtils.dateToString(upper), true, true);
}
