http://steemfriends.org is a popular tool with approximately 20,000 hits per month.

New Features

You can test out the new feature I have added by getting to the Articles Voted or Articles Written section of Steem Friends.

Click on "User History" on the navigation bar, then click on "Written Articles". This will take you to the Article Search form. Alternatively, just go to this link: http://steemfriends.org/articlelist.php?mode=written

From here, you can see the change I have made to the form. It now allows you to enter a combination of tags into the form to search for the article you want, separated by space, as suggestion by @amosbastian.

Let's say you want to find articles that I have written for all of three tags "utopian-io development steemdev" in the last month, you can simply type exactly that into the textbox and the blue button, as shown below:

You can see that results will show up for these articles which match those 3 tags.

Note that the order of the tags is not important in this search, so they do not have to be typed in that order. You can type development utopian-io steemdev and still get the same result.

The same feature has also been applied to the Voted Articles Search. So if you want to find articles which you have voted in the same tag combinations (order doesn't matter), then simply go to the Voted Articles Search page, located here, also accessible from the navigation bar:

https://steemfriends.org/articlelist.php?mode=upvote

You can see below are the articles I have voted for under the tags Life and Nigeria.

How they were implemented:

articlelist.php:

Support for multiple tag separation in one array
After gathering the tag input from the user, the controller will separate the tags into an array using the PHP Explode function before passing it onto the model and view, removing the need for collecting a separate input for tag2.

articlelistview.php:

Remove tag2 input, lengthen tag1 textbox for multiple tag entry
The tag2 input box has been removed. This is because we will now allow users to enter multiple tags in the tag textbox, separated by space. Explanation to this also provided.

articlelistmodel.php:

searchtag() function written for searching multiple tags in database
Added a searchtag() function for use in both written and voted article modes. It searches through the database for multiple tags by using a for loop to add conditions to SQL. It uses the NEAR function to find matching tags in json_metadata so dApps storing info in json_metadata won't interfere with tag search.
