Generate Search Plugin
This plugin creates a form-driven search over the topics of a selected web.
TWiki:Main/TWikiInstallation demonstrates a widely used TWiki application: A search where the search results can be filtered based on parameters entered by the user in a form.
This plugin generates such searches automatically from the field values defined in a
TWikiForms. The user is presented with a table of possible fields and can select whether the field should be shown as the result of the search, and whether it should be possible to filter on that field.
Syntax Rules
- Syntax:
%GENERATESEARCH{"topic" ...}%
- Supported parameters:
Parameter: | Description: | Default: |
"topicregex" | A regular expression determining the topics to be searched | required |
form="..." | The topic defining the field values | Current topic |
web="..." | The webs that will be searched, separated by commas. If there is more than one web, a select is presented to the user that allows to search any single one or all of the indicated webs | Current web |
all="..." | If off , generates a select menu to choose among the possible webs to be searched; if on , all webs (see above) are searched. | on |
title="..." | The heading for the search page generated | |
message="..." | Additional explanatory text to be added before the filter block | |
initial="..." | Determines whether the initial rendering of the search form also executes the search. Possible values are on , off | on |
Example
Below is an example form from
TWikiForms:
Name | Type | Size | Values | Tooltip message |
TopicClassification | select | 1 | NoDisclosure, PublicSupported, PublicFAQ | blah blah... |
OperatingSystem | checkbox | 3 | OsHPUX, OsLinux, OsSolaris, OsWin | blah blah... |
OsVersion | text | 16 | | blah blah... |
If this plugins is installed, the variable
%GENERATESEARCH{topic="Web.*" title="Search knowledge base" initial="off" message="(may use regular expressions)" }%
will expand as follows:
Selecting "Show" for a field will display this field for search results. Selecting "Filter" for a field will allow to filter search results by specific values. If the user were to select all fields (for which the "Select all" short cut can be used), the following query page would be generated:
As can be seen, fields with defined values yield a drop down menu to select the possible values (this works for select, radio, and checkbox fields), while all other fields have a text box to enter values. The search result is filtered such that the form fields contain the filter values. Note that this search uses regular expression, and thus, regular expressions may also be entered as filters. (Note that "Filter" implies "Show".)
