In some examples, a plurality of content properties may be used for managing indexing of object data, such as a plurality of files. Each content property may include an expression for extracting data values from specific data fields in the object data. Further, each content property may include a name that may be used for indexing the objects using the extracted data values. For instance, multiple content properties may have the same name, but may each have different expressions for extracting different data values from different data fields. Accordingly, the content properties may be used to extract desired data values from the objects for indexing. When a search query is received including a content property name and a specified value, one or more of the objects that are indexed with the specified value may be searched.
