404s for search and products

I’m getting 404s (non existing page) from google webmaster tools for links ending:
/woocommerce-search/keyword/
/search-in/product/search-other/product,p_cat,p_tag,post,page

Using Woocommerce, Woo Custom Product Tabs lite, Quotes & Orders and Predictive Search Pro among other plugins.

Help please?
