The invention relates to a biomedical literature content retrieval technology, in particular to a biomedical literature long query content retrieval method and device and computer device.The method comprises the steps that a biomedical literature hierarchical tree is constructed, and child nodes select and store document fragments based on the relevancy between subject terms corresponding to the child nodes and the document fragments of documents in a retrieval library; preprocessing a long query text input by a user to obtain to-be-queried content; performing topic reasoning on the to-be-queried content layer by layer on the biomedical literature hierarchy tree from top to bottom based on a hidden Dirichlet distribution method, namely calculating topic relevancy between the to-be-queried content and other nodes except a root node from top to bottom, and if the relevancy is greater than a set threshold value, continuing to search a next-layer node of the child node; if the queried child node is a leaf node, t
