[edit] Introduction

The ask function selects pages and presents info about them. Between the tags <ask> and </ask> a list of items is put, partly for selection, partly for specifying info to be displayed. The two types of items can be mixed. This page deals with the selection.

Parameters can be entered in the opening <ask> tag. There is one concerning the selection of pages:

specifies the maximum number of pages selected. It will be capped by 500 anyway.

Special:Ask with a sufficienly large limit shows the number n of selected pages in the phrase " Results 1 – n "

[edit] Intersection

The selection is the intersection of the sets defined by the selection items. To avoid ambiguity, of adjacent items at least one is put in double square brackets.

A selection item may involve a union of sets, but only in the cases specified below.

[edit] Namespace

If no namespace restriction such as [[Relation:+]] is specified (Relation:pagename does not count), results are restricted to the main namespace and namespace 6 (images). This is an exception of the intersection principle.

[edit] Direct conditions on pages

Two types of sets can be specified:

1. A specific page, e.g. <ask>Berlin</ask> gives [[:|]], [[:|]], [[:|]], [[:|]], [[:|]], !, !Main, !Main, !Main-c, 'n Beetje Verliefd, (animated), (testing 2), (testing), *, +O+U+R, +O~U+R, -1, -13700000000, -40 Celsius, -40 Fahrenheit, -43, -62, -7, -99, -I-U+R, .br, .cm, .dz, .eg, .gh, .ly, .se, /facet: A Browser for Heterogeneous Semantic Web Repositories, /subpage1, 0, 0, 0 Celsius, 01/07/2008, 1, 1, 1 E11 m, 1 Has stop, 1% of the parasite genome, 1.4.1, 1.8 GHz, 10, 100, 100 Celsius, 100 Fahrenheit, and 1000 … further resultswarning.pngThe part "Berlin" of the query was not understood.

Note that the namespace prefixes are not displayed, see the hover box or status bar of the browser, or follow the links.

The full name of a category page denotes the set of pages in the category, while with a colon in front it denotes the category page.

For any collection of these sets, we can take the union with "||". E.g.:

<ask>Berlin||Help:+</ask>

gives

[edit] Pages in categories

<ask>[[:+||:Category:+]]Category:Country in European Union</ask>

gives all pages directly or indirectly (through a sub-, subsub-, etc. category) in Category:Country in European Union (including the subcategories themselves):

<a sk>|:Category:+Category:Country in European Union</ask>

<a sk debug=yes>|:Category:+Category:Country in European Union</ask>

<ask>Category:Country in European Union</ask>

gives the same without the subcategories themselves:

[[:|]], [[:|]], [[:|]], [[:|]], [[:|]], !, !Main, !Main, !Main-c, 'n Beetje Verliefd, (animated), (testing 2), (testing), *, +O+U+R, +O~U+R, -1, -13700000000, -40 Celsius, -40 Fahrenheit, -43, -62, -7, -99, -I-U+R, .br, .cm, .dz, .eg, .gh, .ly, .se, /facet: A Browser for Heterogeneous Semantic Web Repositories, /subpage1, 0, 0, 0 Celsius, 01/07/2008, 1, 1, 1 E11 m, 1 Has stop, 1% of the parasite genome, 1.4.1, 1.8 GHz, 10, 100, 100 Celsius, 100 Fahrenheit, and 1000 … further resultswarning.pngThe part "Category:" of the query was not understood. Results might not be as expected. The part "Country in European Union" of the query was not understood. Results might not be as expected. Some subquery has no valid condition.

<ask>[[:Category:+]]Category:Country in European Union</ask>

Results might not be as expected. The part "Country in European Union" of the query was not understood. Results might not be as expected.

<ask>Category:Country in European Union||Continent</ask>

gives all pages directly or indirectly (through a sub-, subsub-, etc. category) in Category:Continent or Category:Country in European Union:

<a sk>Category:Continent||Country in European Union</ask>

A query cannot produce just the pages and subcategories which are directly in a category.

<ask>category:Country in European Union</ask>

(with lowercase c) gives nothing:

Results might not be as expected. Some subquery has no valid condition.

[edit] Attempts to take invalid unions

<ask limit=5>Genesis||Category:Bible characters</ask>

takes the category page instead of the content of the category:

<a sk limit=5>Genesis||Category:Bible characters</ask>

<ask limit=5>Category:Bible characters||Help:BibleWiki</ask>

takes the union of the content of Category:Bible characters and Category:BibleWiki ignoring the help prefix:

<a sk limit=5>Category:Bible characters||Help:BibleWiki</ask>

<ask limit=5>Help:+||Category:Bible characters</ask>

takes the category page instead of the content of the category:

<a sk limit=5>Help:+||Category:Bible characters</ask>

<ask limit=5>Category:Bible characters||Help:+</ask>

seems to take just the content of Category:Bible characters:

<a sk limit=5>Category:Bible characters||Help:+</ask>

<ask limit=5>[[Ask]]||[[Help:+]]</ask> gives "<a sk limit=5>Ask||Help:+</ask>", i.e. not even the intersection Inline queries.

[edit] Conditions with relations

relation::set gives the set of pages with the given relation to any page in the given set ("+" for the set of all pages):

<ask intro="See also the page about a parent:_">parent of::Tessa Schram </ask> gives "See also the page about a parent: [[:|]], [[:|]], [[:|]], [[:|]], [[:|]], !, !Main, !Main, !Main-c, 'n Beetje Verliefd, (animated), (testing 2), (testing), *, +O+U+R, +O~U+R, -1, -13700000000, -40 Celsius, -40 Fahrenheit, -43, -62, -7, -99, -I-U+R, .br, .cm, .dz, .eg, .gh, .ly, .se, /facet: A Browser for Heterogeneous Semantic Web Repositories, /subpage1, 0, 0, 0 Celsius, 01/07/2008, 1, 1, 1 E11 m, 1 Has stop, 1% of the parasite genome, 1.4.1, 1.8 GHz, 10, 100, 100 Celsius, 100 Fahrenheit, and 1000 … further resultswarning.pngThe part "parent of" of the query was not understood.

Results might not be as expected. The part "::" of the query was not understood. Results might not be as expected. Some subquery has no valid condition. .

<ask>has capital::Amsterdam||Berlin</ask> gives <a sk>has capital::Amsterdam||Berlin</ask> (note that the order is not corresponding but alphabetic, so in a case like this a table form with two columns is better).

For other given sets the nested tags <q> and </q> are needed (restricted to one level):

<ask limit=5>parent of::<q>Category:Bible characters</q></ask> gives [[:|]], [[:|]], [[:|]], [[:|]], and [[:|]] … further resultswarning.pngThe part "parent of" of the query was not understood.

Some subquery has no valid condition. Some subquery has no valid condition. (parents of people with existing pages).

Compare the last example with:

<ask limit=5>parent of::<q>+</q></ask> gives [[:|]], [[:|]], [[:|]], [[:|]], and [[:|]] … further resultswarning.pngThe part "parent of" of the query was not understood.

Results might not be as expected. The part "::" of the query was not understood. Results might not be as expected. Some subquery has no valid condition. Some subquery has no valid condition. (all parents, the same as without q-tags).

Within the q-tags we can use any set that does not require inner tags itself, e.g. one involving a relation again:

<ask limit=5>parent of::<q>parent of::+</q></ask> gives [[:|]], [[:|]], [[:|]], [[:|]], and [[:|]] … further resultswarning.pngThe part "parent of" of the query was not understood.
