Contextual Search+discussion

1. You can currently only do this using the "+" approach.  However, you can use contextual names to display these in very flexible ways.

2. You can use "_self", "_left", etc  as WQL values.  For example {"refer_to":"_self"}

3. I fixed this.  I'm beginning to thing something went wrong with escaped inclusions in our recent migration from postgres to mysql as part of the architecture shift.  The problem was that there was a reference to {{_self}} that was intended to show as text but was triggering a recursive inclusion!

Here what I want to do:

{"type": "Source", "content": "_self"}

So I want to search for the name of the card in which the search results are to be shown. How can I make this work?

so can you give me an example of a card and what you want to see on it?

The "_self" basically gets replaced with the name of the card in question. So the above would be searching for cards where the content is exactly equal to its name.

See the first query in:

http://wagn.wikirate.org/Oil_Gas

instead of having to write the card's name "Oil & Gas" I want to use _self.

This is what I currently use:

{"type": "Source", "right_plus":[{},{"content": ["match","Oil & Gas"]}]}

This is what I would want to use:

{"type": "Source", "right_plus":[{},{"content": ["match","_self"]}]}

Is that maybe a problem with the "&" ?

oh, now I get what you were saying in the other ticket. More on this soon...

What's the name of this card? If it's "Source - Oil & Gas", then the second search is really equivalent to ....["match","Source -- Oil & Gas"], which would rule out anything that didn't match "Source". I'm guessing it's that "Source" and not the ampersand causing the problem.

i think i get it now. I think what i should use is "_left".

contextual names (_self, _left, _right, etc) are a little weird in the case of searches. Normally in A+B, _self refers to "A+B", but in the case of searches it refers to "A".

This is a legacy issue. I could explain how it got this way, but suffice it to say that there was a reason, and that reason has been wiped away.

We have a ticket to fix it. It's simple in the code; the problem is migrating all the old searches.

by the way, if you ever just want to see what _self is in a given search context, you can just use this WQL:

{"name":"_self"}
