Example 20 with XPathQueryService

the class ValueIndexTest method pathIndexStringMatchingFunctions.

/*
     * Bugfix
     *
     * These following two tests were put in place to demonstrate bugs in how the index matching functions work,
     * as a precursor to a fix, which was committed 2/3/2010. The issue was that the 2nd parameter
	 * to the string matching functions was incorrectly interpreted as a regex, which causd an exception
	 * to be thrown if the string included characters that have special meaning in a regex, eg. '*' for contains.
