Effective Usage: Advanced World Search
Below you will find some hints, how to quickly search the world area.
A Single Term is a single word such as Wuala or friend.
A Phrase is a group of words surrounded by double quoted such as “wuala group”. Multiple terms can be combined together with Boolean operators to form a more complex query.
Boolean Operators
2 Boolean operators are supported: “+” and “-”.
+ Operator:
The “+” operator requires that the term after the “+” symbol must exist somewhere in the field of a single item.
The “+” operator requires that the term after the “+” symbol must exist somewhere in the field of a single item.
To search for items that must contain flower, but may contain tree use the query:
+flower tree
- Operator:
The “-” operator excludes items that contain the term after the “-” symbol.
The search for items that contain flower but not tree use the query:
flower -tree
The search for items that contain flower but not tree use the query:
flower -tree
Wildcard Search
To perform a multiple character wildcard search use the “*” symbol. This search is supported only within single terms, and “*” may not be the first character.
Multiple character wildcard searches looks for 0 or more characters.
For example, to search for test, tests, or tester, you can use the search:
test*
Multiple character wildcard searches looks for 0 or more characters.
For example, to search for test, tests, or tester, you can use the search:
test*
Fuzzy Search
To perform a fuzzy search use the tilde, “~”, symbol at the end of a Single word Term.
For example to search for a term similar in spelling to roam use the fuzzy search:
roam~
This search will find terms like foam and roams.
For example to search for a term similar in spelling to roam use the fuzzy search:

Field
When performing a search you can either specify a field or use the default field. You can search any field by typing the field name followed by a colon “:” and then the term or phrase you are looking for.
To search for the users whose username is Wuala use the query:
user:Wuala
To search for the tag music use the query:
Tags:music
The supported fields are as following:
Name (name of items, such as filename), description, tags, comments, commentAuthors, owner, path, extras (specific meta data such as artist, song title, album, etc.), fullname, email, skype, founder, uploadDate, modificationDate
Grouping
Parentheses are using to group multiple clauses to form sub queries.
To search for either tree or present and Christmas use the query (
+(tree present) Christmas
To search for either tree or present and Christmas use the query (
+(tree present) Christmas
Range Search
Range Queries allow you to match items whose value are between the lower and upper bound specified by the Range Query. Sorting is done lexicographically.
