Search a keyword with a space in it using query rules SharePoint 2013

Question

I have a simple requirement to search based on phone numbers.

Phone numbers of users are stored in their user profiles.

The managed property for phone number is People:PhoneNumber

I have made a query rule to bring people in everything tab as a promoted results. Below is the rule.

PhoneNumber:"{subjectTerms}" OR PhoneNumber:"{subjectTerms}*" 

Following works fine:

1. 1234567890
2. 1234
3. 123*

Following does not work

1. 1234 56789

How can I allow phone numbers having space in it?

Answer 1

That is how crawl works.

If you have PhoneNumber in these format:

1. 1234567890
2. 1234 567890
3. 123 4567 890
4. 123 456 7890

When crawling, every sign or space " ", "-", "_", "(", ")" is like delimiter and it is putted in new place inside array.

For example: for 1. it will be array[0] with (1234567890), for 2. will be array[0 and 1] with (1234 and 567890) because space and for 3. and 4. it will be array[0, 1 and 2] because two spaces.

When you search for example PhoneNumber:"123*" you get all four.

If you search for ex. PhoneNumber:"1234*" you will get only two (1. and 2.).

If you search for ex. PhoneNumber:"12345*" you will get only one (1.) because only 1. contains all chars in one place.

If you search for ex. PhoneNumber:"123 456*" you will get two (3. and 4.).

I hope it's a little more clearly for you how crawl works.
