The implementation of a search engine to find web resources requires the construction of the adequate mathematical model. The vast majority of the developed models are focused on text search. Model should provide the high-speed processing of search queries, conduct a qualitative assessment of the relevance and a ranking-orientability results. Existing systems such as GOOGLE, YAHOO, BING, etc. are using such mathematical models. Each implementation is different and characterized by benefits and drawbacks. Despite the fundamentally especially in the implementation of models, there are several basic approaches. Each approach uses certain principles of processing and presentation of text to the search. The article considers the basic features of the mathematical models that underlie the construction of existing search engines. The article contain model based on sets, vectors, probability and references.
