Sorting Results
- This slider determines how the matched sites are sorted.
- If you want to see the most popular sites that are somewhat related to your search, slide this more towards "popularity."
- If you want to see the sites that best matched your search, regardless of popularity, slide this towards "similarity."
Must Include Tags
- Matched sites will not be shown unless they have all of the tags on this list.
- This feature is useful for when you require a site to have been tagged as something.
- To add a tag to this list, click "add tag" or click on any tag in a result.
Must Not Include Tags
- Matched sites that have any tag on this list will not be shown.
- This feature is useful for filtering out results that have tags you are absolutely not interested in.
- To add a tag to this list, click "add tag" or click on any tag in a result.
Types of Results
- This option lets you specify the types of sites to show.
- If you want to only see domains (www.
.com), select "domains only." - If you want to only see articles (www.
.com/something/here), select "articles only." - If you don't care, or care so much about both, select "Both".
About The Results
an example search result
How moreofit Searches
Each website has a unique tag signature -- a set of words
that users have described the website as. Moreofit searches
for websites that have similar tag signatures and displays the results.
1: Similarity
A site's "similarity" is determined by how well its tag signature matches the tag
signature that is being searched for. A 100% match means that it has the exact same
tags in the exact same order, while a 0% match means it has no tags in common.
2: Popularity
The popularity of a website is, well, pretty much self explanatory.
3: Tag Signature
The tag signatures show how a site is described. The deeper the color of the tag,
the more frequently the website is tagged as this. Tags underlined blue denote a tag
that is in common with the search's tag signature.
