How to avoid double quotes for is equal to when using segment builder

Question

I'm creating a condition for the segment builder inheriting from TypedQueryableStringOperatorCondition.

I'm overriding the method GetResultPredicate to apply my filter like this

return base.GetCompareExpression((IndexedContact c) => c["contact.myfield"], "myvalue");

This is translated into the following query:

contact.myfield:myvalue

So good so far, but if the value I'm looking for has more than one word or pipe to split terms it adds double quotes to the query:

return base.GetCompareExpression((IndexedContact c) => c["contact.myfield"], "my value");

This is translated into the following query:

contact.myfield:"my value"

In my case the query I'm trying to get is:

contact.myfield:my value

To get result containing "my" or "value" I have tried using the Operator contains, but it has been translated into a massive spanNear([SpanWildcardQuery.

Any idea how to achieve the query:

contact.myfield:my value

Trying to make it easier or clearer what I'm really trying to do is to find contacts containing any of the "words" in that field. It's fine If I have to change the approach.

What you need is an "or"-based expression that has a separate condition for every search term:

using Sitecore.ContentSearch.Linq.Utilities;

// ...

IEnumerable<string> keywords = new string[] { "my", "value" };

Expression<Func<IndexedContact, bool>> keywordsPredicate =
    keywords.Aggregate(
        PredicateBuilder.False<IndexedContact>(),
            (current, keyword) => current.Or(
                c => base.GetCompareExpression(c["contact.myfield"], keyword)));

return keywordsPredicate;

Please note that GetCompareExpression() may return different operators. It's up to you what to do when the operator is not "equals".
