Adding a bif:contains SearchProperty

[ethieblin]

Hello,

We would like to discuss the addition of a new Subclass of SearchProperty, which would look like GraphDBSearchProperty, but for Virtuoso (bif:contains instead of the lucene queries).
This would make Sparnatural a bit more Virtuoso-compatible.
We propose to develop that feature for you, if you agree with the following proposal:

What we were thinking of for that new configuration would be:

• the terms input by the user would be transformed into a bif:contains query, e.g., if the user types "jean petit", the bif:contains query would become "'jean' and 'petit'": basically a split on the escape chars, quoting every term found that way and joining them with the keyword "and".

This query processing would have the following advantages:

• instead of having the user learn the quite hard bif:contains syntax (which is not that of a regex, and quite restrictive), it will allow for literal searching whatever the order of the terms are. The "jean petit" input will match with "Petit, Jean - notaire" for example.
• It will also be possible to write a request like "frédéri* phély*", transformed into "'frédéri*' and 'phély*'" which will allow to match literals having terms starting by "frédéri" and "phély"

Sure, go ahead ! See that other discussion on how to implement something similar but for the Jena full-text search syntax, it can give you pointers on where to start: #447

What I will do is that I will create the necessary entries in the configuration ontology for you to plugin the widget code.
But, without waiting for this, what you can do is modify the behavior of the GraphDBSearchWidget so that it generates the query you need:

• placeholder waiting for your implementation: https://github.com/sparna-git/Sparnatural/blob/master/src/sparnatural/components/widgets/SearchRegexWidget.ts#L140

I think you are all set !

Quick question regarding the contribution: I see there is a "pretty" script in the package, however when I run it, it modifies a lot of files in the repository.
Are there any coding rules (linting, formatting) I should follow to contribute ?

[tfrancart]

I don't use this "pretty" script from the package. Don't use it.
There are no specific rules to follow. I trust your "bon sens". I use VSCode as dev environment.

Hello, I think there is a small typo in the URI of http://data.sparna.fr/ontologies/sparnatural-config-core/VirtuosoSearchProperty in the http://data.sparna.fr/ontologies/sparnatural-config-core, it uses a slash as delimiter but in the code you provided, it uses a #

Thanks this is fixed in the ontology
