    Thanks, but this looks perilously close to advertising. What do others think?

    If this was posted somewhere read by a large number of people that need a formula search engine, it probably would qualify as advertisement.

    But context matters, I do not think that explaining what MWS is on this page qualifies as an advertisement.

    I tried to search for some things, but the current description is incomprehensible and lacks examples. Additionally, the provided link that supposedly should have examples does not have any.

    For instance, I searched for

    ?a^*(?b)\to ?c

    which presumably would search for things like f*(A)→B. Instead, it finds formulas like A*×T→S⁢ in the article schedule.

    I don’t understand how the section about MWS is relevant to searching the nLab, which is the subject of the page in question.

    Okay, maybe I should read the whole page; I see from the first section that there is an instance of MWS for the nLab. If MWS is actually useful for searching the nLab, it makes sense to cover it on this page. However, in that case I think the separate text should be condensed and incorporated into that bullet point, e.g.

    nLab Formula Search provides an instance for the nLab of the MathWebSearch engine (a content-based search engine for MathML formulae using Substitution Tree Indexing). To use it… This project is still under development; bug reports and feature requests can be submitted at its github repository.

    Michael and team have been in touch for us for some time (more than a year and a half); Bas is the main person who has been corresponding with them. In particular, Bas invited Michael to edit this page with the express purpose of advertising the tool :-). Yes, there is a version specifically for the nLab. I have not really looked into it myself.

  10. By the way, MathWebSearch is not searching the current nLab but an experimental thing I set up over a year ago. I have notified Michael and his team (I think that when Michael and his team were beginning work on this, they were browsing the nForum, stumbled on the experimental stuff, and must have been confused). This might explain seemingly strange results.

    Have a look at the examples page. It looks quite nice. MWS is available at ZentralBlatt and they’ve kindly provided the tool for the nlab too.

    Re #6, I’m not sure about that example. It seems like a bug, maybe you can report it.

    Hi, there! I was trying to add the nLab built-in search engine to my browser, and the queries are working well. but, I was also hoping to find the "Suggest URL" for the nlab search engine API somewhere on this page. I am here to inquire if this is even implemented?

    That’s not implemented. If you want to add it, you can contribute a pull request to Instiki (here is the current search method), which we can then port to the nLab. Maybe you can rank completion suggestions by number of revisions as a proxy for popularity?
