PsychSpider enables you to limit your search to certain attributes of a document. While indexing the crawled documents PsychSpider extracts zones and fields in documents so that they can be searched. Mime-Type, language, title, keywords, author or URL are such attributes which are kept in zones or fields, so that they become searchable.
To search these fields you can use the Parametric Index or use special search syntax. There is a major difference in the search syntax if the attribute is stored in a zone or in a field. Zones can be searched using the zone name and the relational operator colon (:). Be sure to enclose your search with double quotation marks if it contains spaces, otherwise the part after the space would not be treated as part of your zone search.
To focus on documents by a specific author use the zone 'author'.
Tip of the week: Some terms may have more than one meaning in a query. "Depression" can be the illness or the time of the Great Depression in the US. To get relevant results combining your search term with other words might help (Tip 11).
