Speed Issue For Searching Contacts Using Free Text Logic

[FNIS INDIA]

I have to search my contacts based on free text search logic, as the fields based on which i have to perform search is not supported by ContactsQuery class directly. I have around 1500 contacts in my contact list.

Can any one please let me know if using free text search will cause too much slow speed? Here is the code snippet which i am using :-

ContactsQuery query = new ContactsQuery (ContactsQuery .CreateContactUrl(mye...@mydomain.com));

quer.Query = "id=7777";

Feed<Contact> feed = ContactsRequestObject.Get<Contact>(query);
