### Embodiment 1

[0044] Establish an index library based on the original mathematical dictionary library, index commonly used formulas and corresponding IDs; prepare original data, preprocess the original data, and set the parameter K; input formulas in the browser, and use word segmentation technology to convert them in the background The Latex format is ax^{2}+bx+c=0; run the searcher, and the searcher runs multiple crawlers to search for data in parallel in the webpage; the content contained in the webpage ax^{2}+bx+c= 0 web pages are downloaded, compressed and stored in the original web page database; according to the content, the word segmentation technology is used to decompose it into ax^{2}, bx, c for indexing; according to the content of the web page, combined with the index table and the original mathematical dictionary library, the output is generated Formula; use the KNN algorithm, set the parameter K, and maintain a priority queue with a size of K from large to small according to t...

### Embodiment 2

[0046]Establish an index library based on the original mathematical dictionary library, index commonly used formulas and corresponding IDs; prepare original data, preprocess the original data, and set the parameter K; input formulas in the browser, and use word segmentation technology to convert them in the background The Latex format is \sin\left ( 3x+\frac{\pi}{6} \right ); run the searcher, and the searcher runs multiple crawlers to search data in parallel in the webpage; the webpage contains the content \sin\ The left ( 3x+\frac{\pi}{6} \right ) webpage is downloaded, compressed and stored in the original webpage database; according to the content, it is decomposed into \sin, \left(, 3x, \frac{\pi }{6} , \right ) for indexing; according to the content of the webpage combined with the index table and the original mathematical dictionary library, generate the formula to be output; use the KNN algorithm, set the parameter K, and maintain a Euclidean distance with a size of K A...

### Embodiment 3

[0048] Establish an index library based on the original mathematical dictionary library, index commonly used formulas and corresponding IDs; prepare original data, preprocess the original data, and set the parameter K; input formulas in the browser, and use word segmentation technology to convert them in the background Run the searcher for Latex format \lim_{n\rightarrow \infty}\left ( 1+\frac{1}{n} \right )^{n}, the searcher runs multiple crawlers to process data in parallel in the web page Search; download the webpage containing content \lim_{n\rightarrow \infty}\left ( 1+\frac{1}{n} \right )^{n} in the webpage, compress and store it in the original webpage database; according to the content Use word segmentation technology to decompose it into \lim_{n\rightarrow \infty}, \left ( 1+\frac{1}{n} \right )^{n}) for indexing; combine index table and original Mathematical dictionary library to generate formulas to be output; use KNN algorithm, set parameter K, maintain a priority ...
