The user query for information retrieval should be clear, specific, and relevant to the information being sought. It should use relevant keywords or phrases that accurately represent the information needed and avoid ambiguous or vague language. Additionally, it can benefit from using boolean operators or advanced search techniques to refine the search results.

What is information retrieval?
Information retrieval is the process of accessing and retrieving relevant information from a collection of data sources. It involves searching for and retrieving documents or data that are relevant to a user's query or information need. Techniques such as indexing, querying, and ranking are commonly used in information retrieval systems to make the search process more efficient and effective.

How do you retrieve information from manual system?
An information retrieval process begins when a user enters a query into the system. Queries are formal statements of information needs, for example search strings in web search engines. In information retrieval a query does not uniquely identify a single object in the collection. Instead, several objects may match the query, perhaps with different degrees of relevancy. An object is an entity that is represented by information in a database. User queries are matched against the database information. Depending on the application the data objects may be, for example, text documents, images,[6] audio,[7] mind maps[8] or videos. Often the documents themselves are not kept or stored directly in the IR system, but are instead represented in the system by document surrogates or metadata. Most IR systems compute a numeric score on how well each object in the database match the query, and rank the objects according to this value. The top ranking objects are then shown to the user. The process may then be iterated if the user wishes to refine the query.[9]
Describe Procedural query language and non procedural query language in DBMS?
A query language is a language in which a user requests information from the database. These languages are usually on a level higher than that of a standardprogramming language. Query languages can be categorized as either procedural or non procedural.In a procedural language, the user instructs the system toperform a sequence of operations on the database to compute the desired result.In a non procedural language, the user describes the desired information withoutgiving a specific procedure for obtaining that information.

What allows a user to find information a specific record based on specific characteristics of the information?

By specifying conditions and criteria in the query, the user can filter records that meet the specified requirements, enabling them to locate the information they are seeking efficiently.
What is a document retrieval?
Document retrieval is the process of locating and accessing specific information or documents from a database or system based on a set of search criteria. It involves searching for and retrieving relevant documents to meet a user's information needs efficiently and accurately. It is commonly used in information retrieval systems, digital libraries, and document management systems.
What is a query that extracts data from a table which meets certain specified criteria?
If the criteria is entered in by the user as the query is run, by prompting the user, then it is a Parameter query. Criteria can also be built direct into the query in which case it is a standard Select query.
