Currently we can search with a single tag.

but how can i filter out some activity with 3 tags.

1. Activity A is Tagged with tag A1, tag A2, tag A3.
2. Activity B is Tagged with tag B1, tag A2, tag A3.
3. Activity C is Tagged with tag B1, tag C2, tag A1.

User have to search activities tagged with tag A2 and B1.. so should display Activity B ..because Activity B contains both tags.

Now user have to search activities tagged with tag A2 OR B1.. so should display all the activities containing tag A2 and tag B1.

Allow user to search with more than one tag
