Half a yard of lines to collect or what to do?

Question

Search Engine Optimization

For the first time I collect the semantic core. While collecting, I came to such a concept that you need to collect separately nouns (nomenclature) and separately occurring adjectives and some properties, and then multiply everything ..
So, when multiplying the properties in 3 columns by themselves, the elma.ru service turns out to be about 150 lam values) are 1, 2 and 3 words. And the browser gives out "not enough memory".
I'm thinking of writing a script for multiplication, but in the end, under half a billion rows, where the collector will fly to, isn't it a**ing?
It's just that there can really be phrases like "(sweater) raglan natural cotton", where the sweater is a nomenclature, and the rest is a selection of properties.
So they got 541 (properties).

Answer 1

Unique keys (unique words or phrases!) - root (root), and then collect - a "tree" from each root, adding extensions (adjectives, synonyms, etc.).
Then, based on the root, generate everything you need from the tree.
