# 1. Queries

With the MoinMoin search engine the same search patterns are allowed in the search and title search input fields as in the parameters for the `FullSearch` and the `PageList` macros.

- There may be several search term seperated by white space
  - Terms are combined by default with an AND operation - only pages containing all search term are returned
  - Double or single quotes may be used to include white space into search terms.

- `-` before a search term means NOT - pages containing this term are excluded from the result

- `regex:TERM` is treated as regular expression

- `title:TERM` searches in pages that their titles match TERM

  - Normal search terms do search the titles, too. Matches in titles get more weight as matches in pages.

- `case:TERM` searches case sensitive

- `linkto:TERM` searches for links to TERM

- `title:`, `regex:`, `linkto:` and `case:` may be used in combination in one search term

  - these modifiers may be abbreviated to any length: e. g. `re:`, `t:`, `reg:`, `cas:`, `l:`

  - `-` must be put before any other modifiers

- `or` operator has a lower precedence than the implicit AND

- Parentheses can be used for grouping

## 1.1. Examples

    title:Help macro

searches for help pages that contain the word "macro".

    apple (computer or "operating system")

searches for pages containing the word "apple" and at least one of "computer" or "operating system".

    windows winamp or linux xmms

searches for pages containing both "windows" and "winamp", and also for pages containing both "linux" and "xmms".

    "is text"

Will match "this text" or "is texts". Quotes are used only to include whitespace, and do not mean "exactly this phrase".

    linkto:WindowsPage title:Linux

searches for pages that have "Linux" in the page name and that link to WindowsPage

    r:\bdog\b

searches for the word "dog" and does not find e.g. the word "doggy"

## 1.2. TitleSearch and PageList

- uses the same patterns

- `title:` is virtually added to every search term
