I took a random assortment of 208 films, cancelled through the searching and found it reached 140. 5 of those titles I should have adapted from the IMDB titles, so I just omitted them.
135 films
13 Major or confusing errors
Major/confusing errors
-A Patch of Blue [Repulsion; not found in results]
-Dopperugengâ (Doppelganger) [ReAnimator ... "Re-Animator" works so I think this is fine, I type it that way anyway I just wanted to remove the dash to see the results and it was confusing so here it is]
-error ["The Queen of Sheba" (1952) finds a 2008 tbr page which causes an error in and halts the processing; not found in the lists]
-Uchûjin Tôkyô ni arawaru (Space Men Appear in Tokyo) [Solar Crisis, not found in results, obscure film]
-Quills [found a featurette instead of the film; film not found in the non-batched results
]
-error ["The Witches" found a 2008 tbr page, again halting the searching with an ugly error box; film from 1990 is not even to be found
]
-Meat Loaf: To Hell and Back [Should be To Hell and Back (1955) with Audie Murphy, easy to identify but despite it being non-confusing "To Hell and Back" (1955) was not found among the results]
-The Fog of War: Eleven Lessons from the Life of Robert S. McNamara [search "Fog" as in "The Fog" (1980) ... this found with the search criteria "The Fog", I just used "Fog" for variety in the results, I would consider this pretty minor although confusing]
-"Star Trek" [should have been "Star!" (1968), the search criteria was "Star" but with or without the exclamation mark, it appeared low in the list, this would have had me puzzled]
-Hyde and Hare [searched "Dr Jekyll and Mr Hyde 1941"; not sure why the 1931 version finds but not this, also very interesting is that neither 1931 or 1941 titles appear in the non-batched list minus the year]
-The Arena [searched "Amazons and Gladiators"; not found in the results.
]
-Conspirators of Pleasure [no movie found]
-Charlotte's Web [wrong version; interesting, the original version doesn't appear in the list, maybe Google search omits multiple results that share a similiar name?]
This next batch of errors is just to be comprehensive, but I don't think these can be held against the Google Search...
Easy to identify/minor errors
-"South Park" [TV series, not movie]
-Rambo III [searching for "Rambo 3", found video game, not movie; "Rambo III" works]
-Othello [wrong year version, but to be expected]
-"The X Files" [instead of movie]
-The Guru [wrong version]
-Grudge [wrong version]
-Too Hot to Handle [wrong version]
-Christmas Vacation 2 [search "Christmas Vacation", correct film appears second in results; if you had entered "National Lampoon's" in the title as well, it would have been correct. Shouldn't be too hard to spot this mistake, assuming you don't have the turkey that is the second "Christmas Vacation" movie]
-The Chaplin Revue [should have been the film "Chaplin", but that's an understandable mistake, although it appears pretty far down the list]
I'd like to batch IMDB as well using the same search titles, for a full comparison.
