Description

SubstringComparator valueComp1 = new SubstringComparator("C34");
Filter actAttributeValueFilter1 = new SingleColumnValueFilter(Bytes.toBytes("cf"),
Bytes.toBytes("code"), CompareOp.EQUAL, valueComp1);
SubstringComparator valueComp2 = new SubstringComparator("S72");
Filter actAttributeValueFilter2 = new SingleColumnValueFilter(Bytes.toBytes("cf"),
Bytes.toBytes("code"), CompareOp.EQUAL, valueComp2);
SubstringComparator valueComp3 = new SubstringComparator("S75");
Filter actAttributeValueFilter3 = new SingleColumnValueFilter(Bytes.toBytes("cf"),
Bytes.toBytes("code"), CompareOp.EQUAL, valueComp3);

FilterList multiValueFilters = new FilterList();
multiValueFilters.addFilter(actAttributeValueFilter1);
multiValueFilters.addFilter(actAttributeValueFilter2);
multiValueFilters.addFilter(actAttributeValueFilter3);
Filter multiValueORFilter = new FilterList(FilterList.Operator.MUST_PASS_ONE, multiValueFilters);

replace with:

SubstringsOrComparator orValueComp = new SubstringsOrComparator("C34^S72^S75");
Filter orValueFilter = new SingleColumnValueFilter(Bytes.toBytes("cf"),
Bytes.toBytes("code"), CompareOp.EQUAL, orValueComp);

or

SubstringsAndComparator orValueComp = new SubstringsAndComparator("C34^S72^S75");
Filter orValueFilter = new SingleColumnValueFilter(Bytes.toBytes("cf"),
Bytes.toBytes("code"), CompareOp.NOT_EQUAL, orValueComp);
