The present invention relates to a multi-mode matching method, device, electronic device and storage medium, the method comprising: obtaining a text to be matched; symbolizing the text to be matched into a symbol sequence; matching the child nodes corresponding to each symbol in the symbol sequence in sequence starting from the root node of a dictionary tree, and in the matching process, determining a matching strategy according to each symbol type in the symbol sequence; and obtaining a matching result after the matching is completed in sequence. The present application can convert a regular expression into a symbol sequence by symbolizing the text to be matched into a symbol sequence, and then sequentially matching the symbol sequence on the dictionary tree, and adopting different matching strategies for matching different symbol types, such as matching strategies for interval nodes, active nodes and the like, which are completely consistent with regular grammar, not only with fast matching speed, but also matching based on the expression ability of the dictionary tree, which greatly enhances the expression ability of the pattern and reduces the maintenance cost of the pattern.
