When the query condition involves multiple indexed attributes， TiDB cannot effectively use multiple indexes to generate a more efficient execution plan. After studying the existing solutions of databases， such as PostgreSQL and MySQL， a new type of data access path using multiple indexes simultaneously was proposed in TiDB to solve the problem， namely MultiIndexPath. Firstly， a possible access path named MultiIndexPath for a certain query was generated and its physical plan named MultiIIndexPlan was created， then the cost of this plan was calculated. Secondly， the general execution framework of MultiIndexPath was proposed after combining the architecture and implementation of TiDB. Finally， the Pipeline execution plan was proposed with the condition of conjunctive normal form. The whole work was implemented based on TiDB 3.0 and several experiments were conducted. Experimental results show that the performance of the proposed scheme is improved by at least one order of magnitude compared with the original TiDB when the condition is the disjunctive normal form. With the condition of conjunctive normal form， the performance of the scheme is also better than that of the original TiDB.
