"i love openstack"

By default, each word you type will be searched for individually. You may also try to search an exact phrase by using quotes ("my phrase") to surround a phrase. The search service may allow a certain amount of phrase slop - meaning that if you have some words out of order in the phrase it may still match.

python3.? 10.0.0.* 172.*.4.*

By default, each word you type will match full words only. You may also use wildcards to match parts of words. Wildcard searches can be run on individual terms, using ? to replace a single character, and * to replace zero or more character. 'demo' will match the full word 'demo' only. However, 'de*' will match anything that starts with 'de', such as 'demo_1'. 'de*1' will match anything that starts with 'de' and ends with '1'.

Warning: Wildcard queries place a heavy burden on the search service and may perform poorly.

+apache -apache web +(apache OR python)

Add a '+' or a '-' to indicate terms that must or must not appear. For example '+python -apache web' would find everything that has 'python' does NOT have 'apache' and should have 'web'. This may also be used with grouping. For example, 'web -(apache AND python)' would find anything with 'web', but does not have either 'apache' or 'python'.

python AND apache nginx OR apache web && !apache

You can separate search terms and groups with AND, OR and NOT (also written &&, || and !). For example, 'python OR javascript' will find anything with either term (OR is used by default, so does not need to be specified). However, 'python AND javascript' will find things that only have both terms. You can do this with as many terms as you'd like (e.g. 'django AND javascript AND !unholy'). It is important to use all caps or the alternate syntax (&&, ||), because 'and' will be treated as another search term, but 'AND' will be treated as a logical operator.

python AND (2.7 OR 3.4) web && (apache !python)

Use parenthesis to group different aspects of your query to form sub-queries. For example, 'web OR (python AND apache)' will return anything that either has 'web' OR has both 'python' AND 'apache'.

name:cirros name:cirros && protected:false

You may decide to only look in a certain field for a search term by setting a specific facet. This is accomplished by either selecting a facet from the drop down or by typing the facet manually. For example, if you are looking for an image, you may choose to only look at the name field by adding 'name:foo'. You may group facets and use logical operators.

size:[1 TO 1000] size:[1 TO *] size:>=1 size:<1000

Date, numeric or string fields can use range queries. Use square brackets [min TO max] for inclusive ranges and curly brackets {min TO max} for exclusive ranges.

172.24.4.0/16 [10.0.0.1 TO 10.0.0.4]

IPv4 addresses may be searched based on ranges and with CIDR notation.

web javascript^2 python^0.1

You can increase or decrease the relevance of a search term by boosting different terms, phrases, or groups. Boost one of these by adding ^n to the term, phrase, or group where n is a number greater than 1 to increase relevance and between 0 and 1 to decrease relevance. For example 'web^4 python^0.1' would find anything with both web and python, but would increase the relevance for anything with 'web' in the result and decrease the relevance for anything with 'python' in the result.

The following characters are reserved and must be escaped with a leading \ (backslash): + - = && || > < ! ( ) { } [ ] ^ " ~ * ? : \
