Oftentimes you may have to modify the entered OmniSearch term (fulltext) to deal with special characters or files names with specific conventions. Code in this post extends FulltextPredicateEvaluator to replace "_" (underscore) with " " (space) in search term...

1) Create class apps.experienceaem.assets.core.servlets.SpecialCharacterInFulltextPredicateEvaluator extending com.day.cq.search.eval.FulltextPredicateEvaluator, add the code below...

package apps.experienceaem.assets.core.servlets;

import com.day.cq.search.Predicate;
import com.day.cq.search.eval.EvaluationContext;
import com.day.cq.search.eval.FulltextPredicateEvaluator;
import org.apache.commons.lang3.StringUtils;
import org.osgi.service.component.annotations.Component;

@Component(
factory = "com.day.cq.search.eval.PredicateEvaluator/fulltext"
)
public class SpecialCharacterInFulltextPredicateEvaluator extends FulltextPredicateEvaluator {

public String getXPathExpression(Predicate predicate, EvaluationContext context) {
String searchTerm = predicate.get(predicate.getName());

if(StringUtils.isEmpty(searchTerm) || !searchTerm.contains("_")){
return super.getXPathExpression(predicate, context);
}

searchTerm = searchTerm.replace("_", " ");

predicate.set("fulltext", searchTerm);

return super.getXPathExpression(predicate, context);
}
}
