Deploying Sapphire publicly on a server for use outside of Waterloo.

We need to show predicate suggestions only for predicates and literals only for objects.

Changing the query and its structure to find answers if no answers are found or to find queries that are closely related to what the user is interested in.

Whether it's possible to use a B-Tree or a B+ Tree instead of length bins for typeahead.

Filtering is not supported in UI or in the backend.

Example of Filtering is in bold:
SELECT DISTINCT ?uri
WHERE {
?uri locatedIn New_Jersey .
?uri type City .
?uri numberOfInhabitants ?inhabitants .
FILTER (?inhabitants > 100000) .
}

Example:

PREFIX dbo: <http://dbpedia.org/ontology/>
PREFIX res: <http://dbpedia.org/resource/>
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
SELECT DISTINCT ?uri 
WHERE {
        ?x rdf:type dbo:Album .
        ?x dbo:artist res:Elvis_Presley .
        ?x dbo:releaseDate ?y .
        ?x dbo:recordLabel ?uri .
}
ORDER BY ASC(?y) 
OFFSET 0 LIMIT 1

In the process of finding alternatives to seeds in the query, we need to use Wordnet in addition to finding literals using a similarity function.

Allow the users to add modifiers like COUNT, DISTINCT, etc. to the SELECT textbox.

Or better, allow the user to choose a modifier for any of the SELECT textbox values through the UI. For example, if there is a variable ?movie, a checkbox for this variable is available to mark if the user needs to modify it, then she can choose from a dropdown list the desired modifier. Any other UI suggestion is welcome.
