Type your query using full or partial locators from the bion ontology. All names will be right-aligned: typing garden will match all the entries (two in this case) that end in those letters, namely,
/bion/collection/collection-type/botanical-garden and
/bion/collection/collection-type/zoological-garden.
If a given name matches more than a single term from bion , all matching terms will be included (and connected with an or operator). Type a longer part of a locator path in order to disambiguate names (e.g. use collection-type/botanical-garden instead of just garden).
You may use an asterisk * as a wildcard character to signify 'any number of any characters' anywhere in a given name (e.g. write /bo*gard* or /collection/*ota*garden for /bion/collection/collection-type/botanical-garden).
Whitespace characters may not be part of any name.
You may use the fuzzy logic operators and and or to query for combinations of terms or negate ratings using not:
botanical-garden and z*garden emphasizes all nodes from the target that rate high for both botanical garden and zoological-garden;
botanical-garden or zoological-garden emphasizes all nodes from the target that rate high for either botanical-garden or zoological-garden;
not botanical-garden emphasizes all nodes from the target that rate low for the botanical-garden (and perhaps high for the things you are looking for -- try queries like not zoo* and not plants, then not zoo* and not plants and not fungi to see this effect).

It is possible to normalize ratings using e.g. norm botanical-garden. Normalizing means to put all terms on a par -- for example, the top result for botanical-garden has a rating of +0.88235 (fairly good on a scale from minus one to plus one) but that the top result for zoological-garden has only a score of +0.29412. Notwithstanding shortcomings in the foregoing evaluation process, this expresses the fact that not each single term will have a most likely target that scores globally among the top ratings related to all terms. In order to make up for the relative differences, say e.g. norm botanical-garden and norm zoological-garden to find targets that are important for both terms assuming an equal standing.
Use parentheses () to group sub-expressions where necessary.
